Answer:
23
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
