Answer:

-9

Explanation:

92 = -4 ( 2x - 5 )

Distribute

92 = -8x + 20

Subtract 20 from both sides

92 = -8x + 20

- 20 - 20

20 cancels out

92 - 20 = 72

Simplified

72 = -8x

Divide -8 on both sides so that x is alone

72 = -8x

-8 -8

-8 gets cancelled out

-9 = x

Or you could flip x on the other side and it would be:

x = -9

I hope it helps! Have a great day!

Answer:

x = -9

Explanation:

92 = -4(2x - 5)

92 = -8x + 20

72 = -8x

x = -9

92 = -4(2*-9 - 5)

92 = -4(-18 - 5)

92 = -4(-23)

92 = 92
