type the correct answer in the box. simplify this expression: 4(1 - 3x) + 7x - 8.
Answer
Explanation:
Step1: Distribute 4
$4(1 - 3x)=4\times1-4\times3x = 4-12x$
Step2: Combine like - terms
$(4 - 12x)+7x - 8=(4 - 8)+(-12x+7x)$ $4 - 8=-4$ and $-12x+7x=-5x$ So, $(4 - 8)+(-12x+7x)=-4 - 5x$
Answer:
$-4 - 5x$
