4(4x + 5)
4(4•7+5)
4(28+5)
4(33)
132
$34.80 because, if you add 15+2+21=58x12.00=696x0.05=34.80
We can use the substitution method to solve this problem.
The second equation is

, so we can plug in 2x for 'y' in the first equation:


Multiply:

Combine like terms:

This is the x-value of our solution, we can plug this into any of the two equations to find the y-value:


Multiply:

This is the y-value of our solution. So our entire solution is (3, 6).
