Question

-4z-200/12=-19 помогите решить

Answer 1

$- 4z - frac{200}{12} = - 19$

$- 4 z- 16 frac{8}{12} = - 19 \ - 4z - 16 frac{2}{3} = - 19 \ - 4z = - 19 + 16 frac{2}{3} \ - 4z = - 2 frac{1}{3} \ z = - frac{7}{3} div (- 4)$

$z = frac{7}{3} times frac{1}{4}$

$z = frac{7}{12}$

Ответ: $z = frac{7}{12}$
