-2x%2B5%2B4x=21

Step 1. Combine like terms (in this case x-terms)

%28-2%2B4%29x=5=21

2x%2B5=21

Step 2. Subtract 5 from both sides of the equation

2x%2B5-5=21-5

2x=16

Step 3. Divide 2 to both sides of the equation

2x%2F2=16%2F2

x=8

Step 4. ANSWER: Solution is x=8

I hope the above steps were helpful.
