Question

06 - ( CFS ) probleminhas do 1 grau.

Answer 1

x/2 + 3x+ x/5 +26 = 5x

apos tirar o mmc de toda a equaçao:

5x + 30x +2x +260 = 50x

separando os termos:

260= 13x
x= 20

Answer 2

x+$\frac{x}{2}$+3x+$\frac{x}{5}$+26=5x
$\frac{10x+5x+30x+2x+260}{10}= \frac{50x}{10}$
47x+260=50x
-3x=-260 ·(-1)
x=$\frac{260}{3}$
x=120
