Solve this system of equations.
1= -2x +9y
x = 2y + 2

Answer and Step-by-step explanation:

I will solve your system by substitution.

x=2y+2;1=−2x+9y

Step: Solvex=2y+2for x:

Step: Substitute 2y+2 for x in 1=−2x+9y:

1=−2x+9y

1=−2(2y+2)+9y

1=5y−4(Simplify both sides of the equation)

1+−5y=5y−4+−5y(Add -5y to both sides)

−5y+1=−4

−5y+1+−1=−4+−1(Add -1 to both sides)

−5y=−5

−5y/-5=-5/-5

(Divide both sides by -5)

y=1

Step: Substitute 1 for y in x=2y+2:

x=2y+2

x=(2)(1)+2

x=4(Simplify both sides of the equation)

x=4 and y=1

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000
