Instead of explaining with words, I will list steps that hopefully you can understand!

Step 1: List it as it is so that we can get it correct!

5x + 2 = 8x + 5

Step 2: Subtract 2 from both sides.

2 - 2 = 0
5 - 2 = 3

Step 3: Simplify.

5x = 8x + 3

Subtract 8x from both sides.

5x - 8x = -3x
8x - 8x = 0

Step 4: Simplify.

-3x = 3

Step 5: Divide by -3.

-3 / -3 = 1
3 / (-3) = -1

x = -1

If you need help, let me know and I will gladly assist you!

Answer:

x = -1

Explanation:

Note: when you send a number across it can change it sign. If it is positive it will turn negative.

5x + 2 = 8x + 5

Send 8x across

5x + 2 - 8x = 5

send 2 across

5x - 8x = 5 - 2

- 3x = 3

Divide both sides by - 3

- 3x/- 3 = 3/- 3

- 3 cancel out - 3

x = 3/ - 3

3 divided by - 3 is - 1

x = -1
