Chapter 0.5, Problem 19E

To determine

To solve the equation $\frac{m}{10}+15=21$

Answer to Problem 19E

  $m=60$

Explanation of Solution

Given Information: $\frac{m}{10}+15=21$

Formula Used : Linear equations with one variable

Calculation:

Given equation is

  $\frac{m}{10}+15=21$

To isolate variable m, subtract 15 from both side-

  $\frac{m}{10}+15-15=21-15$

This gives

  $\frac{m}{10}=6$

To simplify further, multiply by 10 both side-

  $\frac{m}{10}\times 10=6\times 10$

This gives

  $m=6\times 10$

Hence the final answer is-

  $m=60$
