Chapter 0.5, Problem 32E

To determine

Solve the equation $5\left(m-1\right)=-25$ and explain each step

Answer to Problem 32E

  $m=-4$

Explanation of Solution

Given information:

  $5\left(m-1\right)=-25$

Formula used:

Simplification of equation

Calculation:

  $5\left(m-1\right)=-25$

Multiply by 5 in bracket

  $5m-5=-25$

To isolate the variable m, adding 5 both sides-

  $5m-5+5=-25+5$

This gives-

  $5m=-20$

To isolate the variable m, dividing by 5 both sides-

  $\frac{5m}{5}=\frac{-20}{5}$

Hence, the final answer is-

  $m=-4$
