5+2x=13

First, combine like terms by subtracting 5 from both sides of the equation.

5 - 5 + 2x = 13 - 5
2x = 8
x = ?

i don't think ur begginning makes sene it wouldn't give u the right answer. can u help me with 5+2x=25?
Answered by Ms. Sue
2x = 8
Divide both sides by 2.

x = 4

To prove this we can substitute 4 for x.

5 + (2 * 4) = 13
5 + 8 = 13

Follow the same procedure for your next problem.

5 - 5 + 2x = 13 - 5

2x = 8
