solve this equation. enter your answer in the box. 3.5z - 2.7z = -6 z =

Explanation:

Step1: Combine like - terms

$3.5z−2.7z=(3.5 - 2.7)z=0.8z$. So the equation becomes $0.8z=-6$.

Step2: Solve for $z$

Divide both sides of the equation $0.8z=-6$ by $0.8$. We get $z=\frac{-6}{0.8}=-\frac{60}{8}=-\frac{15}{2}=-7.5$.

Answer:

$-7.5$
