Question

Помогите срочно плиз!!!
(2/3 + х)÷ 14 = (3/2 + х)÷ 18

Answer 1

$(\frac{2}{3} +x):14=(\frac{3}{2} +x):18$

$\frac{2}{3}:14+\frac{x}{14} =\frac{3}{2}:18+\frac{x}{18}$

$\frac{1}{21} +\frac{x}{14} = \frac{1}{12}+\frac{x}{18}$

$\frac{1}{21}^{/12} +\frac{x}{14}^{/18} = \frac{1}{12}^{/21} +\frac{x}{18}^{/19}$

$\frac{12+18x=21+19x}{252}$

$12+18x=21+19x$

$18x-19x=21-12$

$-x=9$

$x=-9$

Ответ: -9.

Удачи!!!
