Question

ayuda porfa vor con esto que no le entiendo​

Answer 1

A)
10x -10 = x
10x -x = 10
9x = 10
x = 10/9

B)
5x -10 = 5
5x = 10 +5
5x = 15
x = 15/5
x = 3

C)
2x +x +10 = 40
3x +10 = 40
3x = 40 -10
3x = 30
x = 30/3
x =10

D)
x/2 +x/4 = 15
2x +x = 60
3x = 60
x = 60/3
x = 20

E)
x/3 -10 = 10
x -30 = 30
x = 30 +30
x = 60
