Having trouble with this problem. 2a+3a-13=a+3

Step 1. Combine like terms and numbers

2a%2B3a-13=a%2B3

%282%2B3%29a-13=a%2B3

5a-13=a%2B3

Step 2. Add 13 to both sides of the equation to get number on the right side.

5a-13%2B13=a%2B3%2B13

5a=a%2B16

Step 3. Subtract a to both sides of the equation to get a-terms on the left side.

5a-a=a%2B16-a

4a=16

Step 4. Divide 4 to both sides of the equation

4a%2F4=16%2F4

a=4

Check...2a%2B3a-13=a%2B3...2%2A4%2B3%2A4-13=4%2B3...8%2B12-13=7...7=7 which is a true statement.

Step 5. ANSWER: a=4

I hope the above steps were helpful.
