Question

calcule×que 1÷3-×÷2=1÷4 ​

Answer 1

Resposta:

$x = \frac{7}{4}$

Explicação passo-a-passo:

$\frac{1}{3} - \frac{x}{2} = \frac{1}{4} \\\\M.M.C. = 6\\\\\frac{2}{6} - \frac{2x}{6} = \frac{1}{4} \\\\\frac{2x-2}{6} = \frac{1}{4} \\\\4.(2x-2) = 6\\\\8x-8 = 6\\\\8x = 6+8\\\\8x = 14\\\\x = \frac{14}{8} \\\\x = \frac{7}{4}$
