To answer this question you would set this up as an equation with all the information about Al on one side being equal to all the information for Matthew on the other side. This is what it would look like: $25 + $9h= $14h. h represents the number of hours they work. It they each worked 5 hours a week, they would make the same amount of money. I determined this by solving the equation for h. I subtracted 9h on both sides leaving you with $25=5h. H would equal 5 hours.

See image.
Use this idea to write an equation.
2x + 3 + 4x = 63
Combine like terms, Subtract 3, Divide by 6, to solve for x. See image.
Answer:
divide both sides by 1.57 so
x=0.636943y
