Answer:

Step-by-step explanation:

So what we want to do first is expand the left side

5(x+4)

Use Foil

5x + 20

Now lets put everything together

5x + 20 = 7x - 26

Bring the x's to one side

5x + 20 (-5x) = 7x - 26 (-5x)

20 = 2x - 26

Move the constants to one side

20 (+26) = 2x - 26 (+26)

46 = 2x

Now divide by 2

x = 23
