Question

x/2 -3/4=x/5-1/2 É URGENTE!!!!

Answer 1

Explicação passo-a-passo:

$\frac{x}{2} - \frac{3}{4} = \frac{x}{5} - \frac{1}{2}$

$\frac{x}{2} - \frac{x}{5} = \frac{3}{4} - \frac{1}{2}$

$mmc(2.5.4.2) = 20$

$\frac{20 \div 2 \times x}{20} - \frac{20 \div 5 \times x}{20} = \frac{20 \div 4 \times 3}{20} - \frac{20 \div 2 \times 1}{20}$

$\frac{10 \times x}{20} - \frac{4 \times x}{20} = \frac{5 \times 3}{20} - \frac{10 \times 1}{20}$

$\frac{10x}{20} - \frac{4 x}{20} = \frac{15}{20} - \frac{10}{20}$

$10x - 4x = 15 - 10$

$6x = 5$

$x = \frac{5}{6}$
