Mathematics

Slav-nsk [51]4 years ago

Answer:

A) 29/8

Step-by-step explanation:

On the left side of the equals sign, we have five x's and nine -1's.

On the right side of the equals sign, we have three -x's and twenty 1's.

Both sides are equal, so:

5(x) + 9(-1) = 3(-x) + 20(1)

5x − 9 = -3x + 20

Add 3x to both sides.

8x − 9 = 20

Add 9 to both sides.

8x = 29

Divide both sides by 8.

x = 29/8

Answer: x=12

First, you do 8 squared = 4(4+x)

Then, you distribute and becomes a two-step equation.

64=16+4x.

So x=12.

Hope it helps :) Brainliest?
