$\frac{2}{3}$ $x^{}$ - $\frac{1}{4}$ = 7$\frac{3}{4}$
⇔ $\frac{2}{3}$ $x^{}$ = $\frac{31}{4}$ + $\frac{1}{4}$
⇔ $\frac{2}{3}$ $x^{}$ = 8
⇔ x = 8 ÷ $\frac{2}{3}$
⇔ x = 12
Vậy x = 12
Đáp án:
x = 12
Giải thích các bước giải:
$\frac{2}{3}$x - $\frac{1}{4}$ = 7$\frac{3}{4}$
⇔ $\frac{2}{3}$x = 7$\frac{3}{4}$ + $\frac{1}{4}$
⇔ $\frac{2}{3}$x = 8
⇔ x = 8 : $\frac{2}{3}$
