Question

5x-4=2x+2,,,,,5x-2+x=5x-1,,,,,,5x+12=3x+2,,,,,,2(x+3)=x+14

Answer 1

5x-4=2x+2
5x-2x=2+4
3x=6
x=2

5x-2+x=5x-1
5x-5x+x=2-1
x=1

5x+12=3x+2
5x-3x=12-2
2x=10
x=5

2(x+3)=x+14
2x+6=x+14
2x-x=14-6
x=8

Answer 2

5x-4=2x+2
5x-2x=4+2
3x=6
x=6:3
x=2

5x-2+x=5x-1
5x-5x+x=2-1
x=1

5x+12=3x+2
5x-3x=12+2
2x=14
x=14:2
x=7

2 x (x+3)=x+14
2x+6=x+14
2x-x=14-6
x=8
