You also know that she makes an hour babysitting, and you already stated that the number of hours she babysits each week is y.So, the expression describing how much she makes each week babysitting is 15y. So, your second equation tells you how to calculate the amount of money she earns weekly: 30x 15y=120 You can simplify this equation by dividing each term by 15: 2x y=8 So, you now have your two equations and can solve: x y=5 2x y=8 Isolate the x variable in the first equation: x y=5 x=5-y Now, substitute this expression ofx into the second equation and solve for y: 2x y=8 2(5-y) y=8 10-2y y=8 10-y=8 -y=-2 y=2 So, she babysits for 2 hours each week.
