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
