1. x-16 =14
x = 14+16
x= 30
2. 8-2x=20
-2x=20-8
-2x=12
x = -6
3. 5x=1/5
x=1/25
4. 3x+14 = 38
3x=24
x=8
5. 2x-x+6 = -3 -2x
x+2x =-3-6
3x=-9
x=-3
6. 2(x+4)=10
2x+8=10
2x=2
x = 1
7. 2x -3(x-4) = 32
2x-3x+12=32
-x=20
x=-20
8. 14 -6x= 2x-4x-14
-6x+2x=-14-14
-4x = -28
x=7
9. -3(x+2) = -4 -5x
-3x-6 = -4 -5x
2x = 2
x=1
