Question

Porfavor alguém me ajude rapido
a)3(x-2)/4=5x/3
b)13-4(2x-1)=-5(x+2)

Answer 1

a)

$\frac{3(x - 2)}{4} = \frac{5x}{3} \\ \frac{3x - 6}{4} = \frac{5x}{3} \\ \frac{3(3x - 6)}{12} = \frac{20x}{12} \\ 9x - 18 = 20x \\ 9x - 20x = 18 \\ ( - 1) - 11x = 18 \\ 11x = - 18 \\ x = - \frac{18}{11}$

b)

13-4(2x-1)=-5(x+2)

13-8x+4=-5x-10

-3x=-27

x=9
