Step-by-step explanation:

Answer 2

Answer:

9x - 5 (2x -3) = 1 - 2x

9x - 10x + 15 = 1-2 x

-x + 15 = 1 - 2x

2x - x = 1 - 15

x = -14

Hence , X = -14 is the solution of the given equation.

verification : substituting x = -14 in the given equation, we get

LHS = 9×(-14)- 5 [2×(-14)-3] = -126 -5 (-28 - 3)

$= \: - 126 - 5( - 31) = \: - 126 + 155 = 29 \\ \\ RHS = \: 1 - 2 \times ( - 14) = 1 + 28 = 29 \\ \\ LHS = RHS$
