To solve by elimination you need to solve for each variable, in this case x, y, and z
x = 1/3
y = 7/3
z = 0
What’s the question/problem?
Answer: 60 units²
Step-by-step explanation:
The total area of the rectangle is equal:
(4+4)*(9+3)=
8*12=
96 units²
The area of the unpainted part of the rectangle is equal:
4*9=
36 units²
The area of the shaded region is equal:
96-36=
60 units²
