ecuaciones

x : 2 - 4 .12 = 8

20 : 4 + 3 . x = 59

5. x + 19 =64

Answer 1

x / 2 - 4 (12) = 8
x/2-48=8
x/2=8+48
x/2=56
x=2(56)
x=112
...................................................
20/4 + 3x = 59
5+3x=59
3x=59-5
3x=54
x=54/3
x=18
.................................
5x + 19 =64
5x=64-19
5x=45
x=45/5
x=9
