Question

$-8 + 3(x + 2) = -(-7x + 9) - 9$

Explanation:

Step1: Expand both sides

Left side: $-8 + 3(x + 2)=-8 + 3x + 6 = 3x - 2$
Right side: $-(-7x + 9)-9 = 7x - 9 - 9 = 7x - 18$

Step2: Move terms with x to left and constants to right

$3x - 7x=-18 + 2$

Step3: Simplify both sides

$-4x=-16$

Step4: Solve for x

$x=\frac{-16}{-4}=4$

Answer:

$x = 4$
