Question

The solution to 4+16=-5(4x-4)

Answer 1

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

Multiply the bracket by -5

(-5)(4)(-5)(-4)

4+16=-20x+20

20=-20x+20

Move +20 to the left side. Sign changes from +20 to -20.

20-20=-20x+20-20

0=-20x

Divide by -20 for both sides

0/-20=-20/-20x

x=0

Answer: x=0

Answer 2

Explanation:

20=-5(4x-4)

-20/5 =4x-4

-4=4x-4

0=4x

0=x
