16=4x-4

To solve for x, you have to get the variable alone on one side. First, add 4 to both sides of the equation.

20=4x

Finally, divide each side by 4

5=x
x=5 (C)

To check your answer, substitute 5 as x into the equation.

16=4x-4
16=4(5)-4
16=20-4
16=16

x=5

The correct answer is C.

Hope this helped! :)
16 = 4x - 4

1. Add '4' to both sides

[tex]16 + 4 = 4x - 4 + 4[/tex]

[tex]20 = 4x[/tex]

2. Divide '4' to both sides

[tex] \frac{20}{4} = \frac{4x}{4} [/tex]

[tex]5 = x[/tex]

The answer is C.
