Question

como resolvo essa equação??? hellllp!!!​

Answer 1

Resposta:

X= (-21)

Explicação passo-a-passo:

$\frac{(X-5)}{10} +\frac{(1-2X)}{5} =\frac{(3-X)}{4} \\\\\\20(\frac{(X-5)}{10}+\frac{(1-2X)}{5})=20.\frac{(3-X)}{4} \\\\20.\frac{X-5}{10}+20.\frac{1-2X}{5}=5(3-X) \\\\2(X-5)+4(1-2X)=5(3-X)\\\\2X-10+4-8X=15-5X\\\\-6X-6=15-5X\\\\-6X+5X=15+6\\\\-X=21\\\\X=-21$
