x+3=15
x=12
3x+2-1=10
3x+2=11
3x=9
x=3
2x+2x+3=15
2x+2x=12
4x=12
x=3
x(3+2)=20
x*5=20
x=4
2*3x+6=102
2*3x=108
54=3x
x=18

Answer 2

x+3 = 15 => x = 15-3 => x = 12

3x+2-1 = 10 => 3x = 10-1 => 3x = 9 => x = 9:3 => x =3

2x+2x+3 = 15 => 4x = 15-3 => 4x = 12 => x = 12:4 => x =3

x(3+2) = 20 => 5x = 20 => x = 20:5 => x = 4

2*3x+6 = 102 => 6x = 102-6 => 6x = 96 => x = 96:6 => x = 16
