Question

X/3 + X/2 = 5/2
A) 2X=5
B)5X=15
C)X=2
D)X=15

Answer 1

Resposta:

$X/3 + X/2 = 5/2 \\ \frac{2x + 3x}{6} = \frac{5}{2} \\ 30 = 4x + 6x \\ x = 3$

A) X=2,5

B) X=3

ALTERNATIVA B

Answer 2

Resposta:

$x = 3$

Explicação passo-a-passo:

$\frac{x}{3} + \frac{x}{2} = \frac{5}{2 \: } = mmc = 6$

$2x + 3x = 15 \\ 5x = 15 \\ x = \frac{15}{5} = 3$

a) 2x=5

x=5/2=2,5
