Question

2x/4 + 9/2 = 4x/3 - 18

Answer 1

2x/4 + 9/2 = 4x/3 - 18
mmc 4,2 e 3 = 12
6x/12 + 54/12 = 16x/12 - 216/12
6x + 54 - 16x + 216 = 0
- 10x + 270 = 0 .(- 1)
10x - 270 = 0
10x = 270
x = 270/10
x = 27

Answer 2

m .m.c. = 12
6 X / 12 + 54 /12 = 16 ×/12 - 216 /12
eliminar o denominador
6 X +54 = 16 X - 216
16 X - 216 =6 X +54
16 X - 6 X = 54 + 216
10 X = 270
X = 270 /10
X = 27
