Answer:
x = 1.8/[tex]\frac{9}{5\\}[/tex]
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/[tex]\frac{9}{5\\}[/tex]
