Question

-1.5(-4x-4)=4x-2(-5x+8.7)+9

Answer 1

Answer:

x = 1.8/$\frac{9}{5\\}$

Step-by-step explanation:

-1.5(-4x-4) = -1.5(-4x) + -1.5(-4) = 6x + 6

The negatives cancel each other out.

4x-2(-5x+8.7)+9 = 4x + -2(-5x) + -2(8.7) + 9 = 4x + 10x -17.4 + 9 = 14x -8.4

6x + 6 = 14x -8.4

-14x        -14x

-8x + 6 = -8.4

-6            -6

-8x = -14.4

/-8       /-8

x = 1.8/$\frac{9}{5\\}$
