Answer:
(7,18)
Explanation:
I think that you are asking for a solution to both equations
-2x + y = 4 → x -2 → 4x -2y = -8
-5x + 2y = 1 → (+) -5x + 2y = 1
-x = -7
x = 7
Substitute 7 for x in either of the two equations and solve for y.
-2(7) + y = 4
-14 + y = 4 Add 14 to both sides
y = 18
The solution is (7,18).
Check:
-2x + y = 4
-2(7) + 18 = 4
-14 + 18 = 4
4=4 Checks.
-5x + 2y = 1
-5(7) + 2(18) = 1
-35 + 36 = 1
1 = 1 checks
