Question

A) 5m-7-2m-2=0


B) 10x-11=7x +4


C)3. (x -2) = x +12



D) 6x = 2 + 36



E)5.(x - 2) = 2x +14

Answer 1

5m-7-2m-2=0
3m-9=03m=9
m=9/3
m=3

10x-11=7x +4
10x-7x=11+4
3x=15
x=15/3
x=5

3. (x -2) = x +12
3x-6-x=12
2x=12+6
2x=18
x=18/2
x=9

6x = 2 + 36
6x=38
x=38/6 simplifica por 2
x=10/3

5.(x - 2) = 2x +14 
5x-10-2x=14
3x=14+10
3x= 24
x=24/3
x=8
