Solve the equation by combining like terms. show all the steps.

2(2x - 4) + x = 7

2(2x - 4) + x = 7

First of all, apply the distributive property for the parenthesis:
a(b - c) = ab - ac

So, = 4x - 8 + x = 7

Now, bring like terms together:
4x + x = 7 + 8

5x = 15

x = 15/5

x = 3

In short, Your Final Answer would be: 3

Hope this helps!
