To solve the given system using the substitution method:
Step 1: Solve one equation for one variable. Let's solve the first equation for x:
x = 2 - 2y
Step 2: Substitute the expression for x into the second equation:
(2 - 2y) - 9y = -9
Step 3: Solve for y:
2 - 2y - 9y = -9
11y = 11
y = 1
Step 4: Substitute the value of y back into the expression for x:
x = 2 - 2(1)
x = 2 - 2
x = 0
So the solution is:
(x, y) = (0, 1)
Therefore, the answer is:
C. (0,1)
