3x - 20 + 2x = 10
Combine like terms: 5x - 20 = 10
Add 20 to both sides: 5x = 30
Divide by 5: x = 6
-x - 5 + 3x = 3
Combine like terms: 2x - 5 = 3
Add 5 to both sides: 2x = 8
Divide by 2: x = 4
x - 8 + 2x = 7
Combine like terms: 3x - 8 = 7
Add 8 to both sides: 3x = 15
Divide by 3: x = 5
-6 - x + 3x = 2
Combine like terms: -6 + 2x = 2
Add 6 to both sides: 2x = 8
Divide by 2: x = 4
-5 + 3x + x = 7
Combine like terms: -5 + 4x = 7
Add 5 to both sides: 4x = 12
Divide by 4: x = 3
-2 + 3x - 2x = 4
Combine like terms: -2 + x = 4
Add 2 to both sides: x = 6
3x - 7 + 2x = 18
Combine like terms: 5x - 7 = 18
Add 7 to both sides: 5x = 25
Divide by 5: x = 5
-16 + x + 3x = 8
Combine like terms: -16 + 4x = 8
Add 16 to both sides: 4x = 24
Divide by 4: x = 6
-2 + x + 2x = 7
Combine like terms: -2 + 3x = 7
Add 2 to both sides: 3x = 9
Divide by 3: x = 3
-x - 3 + 2x = 3
Combine like terms: x - 3 = 3
Add 3 to both sides: x = 6
