Answer:
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
