Add like terms.
4x - 2x = 2x
6 - 5 + 9 = 10
2x + 10
If you have to solve for x (if you need one number for a value) -
Set equal to 0.
2x + 10 = 0
Subtract 10 from both sides.
2x = 10
Divide 2 by both sides.
x = 5
4x - 2x = 2x
6 - 5 + 9 = 10
2x + 10
If you have to solve for x (if you need one number for a value) -
Set equal to 0.
2x + 10 = 0
Subtract 10 from both sides.
2x = 10
Divide 2 by both sides.
x = 5
