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
