Question

a metade do numero x adicionada a terça parte do mesmo numero x é igual a 35

Answer 1

1/2x+1/3x=35
mmc
3x+2x=210
5x=210
x=42

Answer 2

$\frac{x}{2} + \frac{x}{3} = 35$                           MMC: 2;3
$\frac{3x + 2x}{6}=35$                                                  2,3 ∫2
3x+2x=35.6                                                                               0,3 ∫
5x=210                                                                                      0,0 ∫
$x= \frac{210}{5}$                                                               ∫S=3x2=6
x=42
Prova real: $\frac{42}{2}+ \frac{42}{3} = 35$
21+14=35
