Answer:
-2(9x-8)
Step-by-step explanation:
We are to simplify the expression -3.1x+7-7.4x-1.5x-6(x-3/2)
Open the parenthesis
-3.1x+7-7.4x-1.5x-6(x-3/2)
= -3.1x+7-7.4x-1.5x-6x+6(3/2)
= -3.1x+7-7.4x-1.5x-6x+9
Collect like terms
= -3.1x-7.4x-1.5x-6x+7+9
= -12x-6x+16
= -18x+16
= -2(9x-8)
Hence the simplified form of the expression is -2(9x-8)
