Question

Resolva a equação: 3(x-1)-2x/5 = 5(x-3)/6

Answer 1

Resposta:

Explicação passo a passo:

$3\left(x-1\right)-\frac{2x}{5}=\frac{5\left(x-3\right)}{6}\\3\left(x-1\right)\cdot \:30-\frac{2x}{5}\cdot \:30=\frac{5\left(x-3\right)}{6}\cdot \:30\\90\left(x-1\right)-12x=25\left(x-3\right)\\78x-90=25x-75\\78x-90+90=25x-75+90\\78x-25x=25x+15-25x\\53x=15\\\frac{53x}{53}=\frac{15}{53}\\x=\frac{15}{53}$
