Answer:
(2,4)
Step-by-step explanation: There are several ways to do this, but one of them is this:
You multiply 9x + y = 4 by 2 to get 18x + 2y = 8
Then subtract the entire equation from the second equation (the first step was done so the y's could be canceled out)
-6x + 2y = -4
- 18x + 2y = 8
You can cancel out the 2y's and then subtract. You are left with -24x = -12. You can then divide each side each side by -12. You would have x = 2. The last step is to plug 2 as x into one of the equations
ex.
-6(2) + 2y = -4
-12 + 2y = -4
2y = 8
y = 4
(x,y) = (2,4)
