Solve: 4x+3 = 2x + 9

4x+3 = 2x + 9

4x-2x=9-3

2x=6

x=6/2

x=3

Move 2x to the left hand side of the equation by subtracting 2x from both sides.

4x+3-2x=9

Add 4x and - 2x to get 2x.

x+3=9

Since 3 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 3 from both sides.

2x=-3+9

Add - 3 and 9 to get 6.

2x=6

Divide each term in the equation by 2.

x=3

x is equal to 3
