Question

Practice Set 12.1
Each equation is followed by the values of the variable. Decide whether
these values are the solutions of that equation.
(1) x - 4 = 3, x = -1, 7, -7
(2) 9m = 81, m = 3, 9, -3
(3) 2a + 4 = 0, a = 2, -2,1
(4) 3 - y = 4,
y = -1, 1, 2
Solve the following equations.
(1) 17p - 2 = 49 (2) 2m + 7 = 9
(3) 3x + 12 = 2x - 4
9x
(4) 5(x – 3) = 3(x + 2) (5) + 1 = 10.
