The answer is x^2=20
First you subtract 4and you get -x^2=-20
Then you divide by -1 which get you x^2=20
Answer:
infinitely many solutions
Step-by-step explanation:
Given the 2 equations
2x + 2y = 18 → (1)
x + y = 9 → (2)
Equation (1) is twice (2)
Thus the equations are equal and will have infinite solutions
