Question

Solve: 5x -2 = 2x + 7

Answer 1

Subtract both sides by 2x:

5x - 2x - 2 = 2x - 2x + 7
3x - 2 = 7

Add both sides by 2:

3x - 2 + 2 = 7 + 2
3x = 9

Divide both sides by 3:

3x/3 = 9/3
\(\boxed{x = 3}\)

You're welcome :)

Answer 4

5x-2=2x+7
Subtract 2x from 5x which makes 2x cancel out
Then now you have 3x
Drop down the rest of the equation which is
3x-2=7
Add 2 to both sides
This makes 2 cancel out
7+2=9 drop down the rest of the equation which is
3x=9
Divide 3 from both sides you should have x=3
