What is 4 (2x-3) + 5x=2x+21?

x=3

Step-by-step explanation:

4 (2x-3) + 5x=2x+21

(4) (2x) + (4) (-3) + 5x=2x+21 (Distribute)

8x+-12+5x=2x+21

(8x+5x) + (-12) = 2x+21 (Combine Like Terms)

13x+-12=2x+21

13x-12=2x+21

Step 2: Subtract 2x from both sides.

13x-12-2x=2x+21-2x

11x-12=21

Step 3: Add 12 to both sides.

11x-12+12=21+12

11x=33

Step 4: Divide both sides by 11.

11x = 33

/11 / 11

x=3
