Question

Resolva a equação X/3+ x/2 = 5/2
Por favor urgente!

Answer 1

Explicação passo-a-passo:

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

$6( \frac{x}{3} + \frac{x}{2} ) = 6 \times \frac{5}{2}$

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

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

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

$2x + 3x = 3 \times 5$

$2x + 3x = 15$

$5x = 15$

$x = \frac{15}{5}$

$\red{x = 3}$
