Question

como resolver essa equação  $x+ \frac{x}{4}=36$

Answer 1

x + $\frac{x}{4}$ = 36

tira mmc = 4

4x + x = 144
       4

corta o 4

4x + x = 144

5x = 144

x = $\frac{144}{5}$ ou x = 28,8

Answer 2

$x+\dfrac{x}{4}=36$

$4\times\left(x+\dfrac{x}{4}\right)=4\times36$

$4x+x=144$

$5x=144$

$x=\dfrac{144}{5}$

$x=28,8$
