Answer:
x=5
y=7
Step-by-step explanation:
y = x+2 so plug that in the next equation as y
so it be --> 5x+(-4)(x+2)= -3 now use distributive property
(-4 times x)+(-4 times 2)= -4x+-8 replug that back in
5x-4x+-8 = -3 subtract your x
1x = x so ---> x+-8 = -3 now to get rid of -8 we have to add 8 to it
x= -3 but whatever you do to one side u do to the other so u have to add 8 to -3---> so it be x=5
now take that x=5 and plug it in to your first eqaiuton to get y
y=5+2 ---> y =7

This equation can be set up letting x be the hourly rate:40x+1.5x(52-40)=638 [40 times the rate, plus 1.5 times the rate for the hours over 40 equals the pay]40x+78x-60x=63858x=638x=11 hourly rate is $11/hr
