(10,30)

x=10

y=30

Step-by-step explanation:

Looking at the first one we know exactly what y is equal to in terms of x so whenever we need a y in the second equation we can just replace it with 3x which means we have

-.5x+35=3x

Solve for x and get

35=3.5x

10=x

We can then plug this x value into the first equation and solve for y

y=10*3

y=30

our answer is therefore (10,30)

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

i hope this is what you were looking for.
