Question

Как решить это уравнение

Answer 1

$frac{3.6}{x - 1.2} = frac{7.8}{6.5}$
$3.6 times 6.5 = 7.8(x - 1.2) \ (1.2 times 3) times 6.5 = \ = 6.5 times 1.2 times (x - 1.2) \ 3 = x - 1.2 \ x = 3 + 1.2 \ x = 4.2$

Answer 2

$frac{3.6}{x - 1.2} = frac{7.8}{6.5} \ 3.6 times 6.5 = 7.8 times (x - 1.2) \ x - 1.2 = frac{3.6 times 6.5}{7.8} \ x = frac{1.8 times 6.5}{3.9} + 1.2 \ x = 4. 2$
