2(2x - 4) + x = 7 solve by combining like terms show all steps plz

2(2x−4)+x=7
2(2x−4)+x=7
5x−8=7
5x−8+8=7+8

5x=15
5x5=155

x=3

2(2x - 4) + x = 7
Distribute the 2
4x - 8 + x = 7
combine like terms
5x - 8 = 7
add 8 to both sides
5x = 15
divide both sides by 5
x =3

CHECK
2(2*3-4) + 3  ?=? 7
2(6-4) + 3  ?=? 7
2(2) + 3 ?=? 7
7 = 7 CHECKS

Yes you are right the correct answer is b
