x-5=2 , 2+5=x , x=7
2x=8 , 8:2x , 2x = 4 , x = 2
3x+5=11 , 11-5=3x , 3x = 6
4x - 3 =2x+7 , 2x - 10, 10:2x , 2x = 5
a) x - 5 = 2
x = 2 + 5
x = 7
b) 2x = 8 |:2
x = 4
c) 3x + 5 = 11
3x = 11 - 5
3x = 6 |:3
x = 2
d) 4x - 3 = 2x +7
4x -2x = 7 + 3
2x = 10 |:2
x = 5
x = 2 + 5
x = 7
b) 2x = 8 |:2
x = 4
c) 3x + 5 = 11
3x = 11 - 5
3x = 6 |:3
x = 2
d) 4x - 3 = 2x +7
4x -2x = 7 + 3
2x = 10 |:2
x = 5
