Question

resolva a equação do 1 grau: 2x/3-1/2=5x/2+4/3

Answer 1

$\frac{2x}{3} - \frac{1}{2} = \frac{5x}{2} + \frac{4}{3} \\ \\ \\ mmc=6 \\ \\ 4x-3=15x+8 \\ \\ 4x-15x=8+3 \\ \\ -11x=11 \\ \\ x= \frac{11}{-11} \\ \\ \\ x=-1$

Answer 2

2x - 1 = 5x + 4 
 3    2     2     3

mmc (2, 3) = 6

4x - 3 = 15x + 8
4x - 15x = 8 + 3
- 11x = 11
x = 11 : (- 11)
x = - 1
