AP State Syllabus 6th Class Maths Solutions 7th Lesson Introduction to Algebra Ex 7.3<\/h2>\n

Question 1.
\nIdentify which of the following are equations.
\ni) x – 3 = 7
\nii) l + 5 > 9
\niii) p – 4 < 10
\niv) 5 + m = -6
\nv) 2s – 2 = 12
\nvi) 3x + 5
\nAnswer:
\ni) x – 3 = 7
\nWe know that, a mathematical statement involving equality symbol is called an equation.
\nx – 3 = 7 has equality symbol. So, it is an equation.<\/p>\n

ii) l + 5 > 9
\nWe know that, a mathematical statement involving equality symbol is called an equation.
\nl + 5 > 9 has no equality symbol.
\nSo, it is not an equation. [It is an inequation]<\/p>\n

\"AP<\/p>\n

iii) p – 4 < 10
\nWe know that, a mathematical statement involving equality symbol is called an equation.
\np – 4 < 10 has no equality symbol.
\nSo, it is not an equation. [It is an inequation]<\/p>\n

iv) 5 + m = – 6
\nWe know that, a mathematical statement involving equality symbol is called an equation.
\n5 + m = – 6 has equality symbol.
\nSo, it is an equation.<\/p>\n

v) 2s – 2 = 12
\nWe know that, a mathematical statement involving equality symbol is called an equation.
\n2s – 2 = 12 has equality symbol.
\nSo, it is an equation.<\/p>\n

vi) 3x + 5
\nIt is only an expression. It\u2019s not an equation.<\/p>\n

Question 2.
\nWrite LHS and RHS of the following equations.
\ni) x – 5 = 6
\nii) 4y = 12
\niii) 2z + 3 = 7
\nAnswer:
\ni) x – 5 = 6
\nGiven equation is x – 5 = 6
\nLHS = x – 5
\nRHS = 6<\/p>\n

ii) 4y = 12
\nGiven equation is 4y = 12
\nLHS = 4y
\nRHS = 12<\/p>\n

iii) 2z + 3 = 7
\nGiven equation is 2z + 3 = 7
\nLHS = 2z + 3
\nRHS = 7<\/p>\n

\"AP<\/p>\n

Question 3.
\nSolve the following equation by Trial & Error Method.
\ni) x + 3 = 5
\nii) y – 2 = 7
\niii) a + 4 = 9
\nAnswer:
\ni) x + 3 = 5
\nGiven equation is x + 3 = 5
\nIf x = 1, then the value of x + 3 = 1 + 3 = 4 \u2260 5
\nIf x = 2, then the value of x + 3 = 2 + 3 = 5 = 5
\nFrom the above when x = 2, then both LHS and RHS are equal.
\n\u2234 Solution of the equation x + 3 = 5 is x = 2<\/p>\n

ii) y – 2 = 7
\nGiven equation is y – 2 = 7
\nIf y = 1, then the value of y – 2 = 1 – 2 = -1 \u2260 7
\nIf y = 2, then the value of y – 2 = 2 – 2 = 0 \u2260 7
\nIf y = 3, then the value of y – 2 = 3 – 2 = 1 \u2260 7
\nIf y = 4, then the value of y – 2 = 4 – 2 = 2 \u2260 7
\nIf y = 5, then the value of y – 2 = 5 – 2 = 3 \u2260 7
\nIf y = 6, then the value of y – 2 = 6 – 2 = 4 \u2260 7
\nIf y = 7, then the value of y – 2 = 7 – 2 = 5 \u2260 7
\nIf y = 8, then the value of y – 2 = 8 – 2 = 6 \u2260 7
\nIf y = 9, then the value of y – 2 = 9 – 2 = 7 = 7
\nFrom the above when y = 9, the both LHS and RHS are equal.
\nSolution of the equation y – 2 = 7 is y = 9<\/p>\n

\"AP<\/p>\n

ii) a + 4 = 9
\nGiven equation is a + 4 = 9
\nIf a = 1, then the value of a + 4 = 1 + 4 = 5 \u2260 9
\nIf a = 2, then the value of a + 4 = 2 + 4 = 6 \u2260 9
\nIf a = 3, then the value of a + 4 = 3 + 4 = 7 \u2260 9
\nIf a = 4, then the value of a + 4 = 4 + 4 = 8 \u2260 9
\nIf a = 5, then the value of a + 4 = 5 + 4 = 9 = 9
\nFrom the above when a = 5, the both LHS and RHS are equal.
\n\u2234 Solution of the equation a + 4 = 9 is a = 5<\/p>\n","protected":false},"excerpt":{"rendered":"
