[tex] \frac{3}{4} x + \frac{1}{2} = - \frac{3}{4} x + 2 \\ \frac{3}{4} x + \frac{3}{4} x = 2 - \frac{1}{2} \\ \frac{6}{4} x = \frac{3}{2} \\ x = \frac{3}{2} \times \frac{4}{6} \\ x = 1[/tex]
comprobamos
[tex] \frac{3}{4} x + \frac{1}{2} = - \frac{3}{4} x + 2 \\ \frac{3}{4} (1) + \frac{1}{2} = - \frac{3}{4} (1) + 2 \\ \frac{3}{4} + \frac{1}{2} = - \frac{3}{4} + 2 \\ \frac{5}{4} = \frac{5}{4} [/tex]
3/4x + 1/2 = -3/4x + 2
4.(3/4x + 1/2) = 4.(-3/4x + 2)
3x + 2 = -3x + 8
3x + 3x = 8- 2
6x = 6
x = 6 : 6
x = 1

Verified answer
3/4x + 1/2 = -3/4x + 2
4.(3/4x + 1/2) = 4.(-3/4x + 2)
3x + 2 = -3x + 8
3x + 3x = 8- 2
6x = 6
x = 6 : 6
x = 1
