Question

Determine o valor da expressão:

4x/3+3/2-1=-3/2+x/3

a) 3

b) -6/5

c) 6/5

d) -2

e) 2​

Answer 1

Letra D

$\frac{4x}{3} + \frac{3}{2} - 1 = - \frac{3}{2} + \frac{x}{3} \\ \\ \frac{4x}{3} + \frac{1}{2} = - \frac{3}{2} + \frac{x}{3} \\ \\ 8x + 3 = - 9 + 2x \\ 8x - 2x = - 9 - 3 \\ 6x = - 12 \\ x = - 2$
