"If 4 is added to a number and the sum is tripled the results 16 more than the number" means that 3%28x%2B4%29=x%2B16


3%28x%2B4%29=x%2B16 Start with the given equation.


3x%2B12=x%2B16 Distribute.


3x=x%2B16-12 Subtract 12 from both sides.


3x-x=16-12 Subtract x from both sides.


2x=16-12 Combine like terms on the left side.


2x=4 Combine like terms on the right side.


x=%284%29%2F%282%29 Divide both sides by 2 to isolate x.


x=2 Reduce.
