Question

equação linear:

1/2 + $\frac{3}{5} x$ - 2(x + 2/3) = 5

gabarito: -25/6

ajuda com a resolução, por favor

Answer 1

$\triangleright{} \frac{1}{2} +\frac{3x}{5} -2x-\frac{4}{3} =5\\\\ \boxed{\boxed{m.m.c(2,3,5)=30}}\\\\ \frac{15+(6*3x)-(2x*30)-(10*4)}{30}=\frac{30*5}{30}\\\\ 15 + 18x - 60x - 40 = 150\\\\ -42x = 150+40-15\\\\ -42x = 175\\\\ \boxed{x = -\frac{25}{6}}$
