Question

4x-1/2x+19 = 2x+1/2x+11

Answer 1

La ecuación que tienes es:
4x-1/2x+19 = 2x+1/2x+11
4x - x/2 + 19 = 2x + x/2 + 11

 8x - x + 38            4x + x + 22
------------------- = -------------------
       2                          2

2 (8x - x + 38) = 2 (4x + x + 22)
2 (7x + 38) = 2 (5x + 22)
14x + 76 = 10x + 44
14x - 10x = 44 - 76
4x = - 32
x = - 32/4
x = - 8

Respuesta.
x = - 8

Answer 2

8x-1x+38/2=4x+1x+22/2
7x+38/2=5x+22/2
2(7x+38)=2(5x+22)
14x+76=10x+44
14x-10x=-32
4x=-32
×=-8
