Answer:
(x, y) = (1, -6)
Explanation:
The expression for y given by the first equation can be substituted into the second equation.
11x +(-8x +2) = 5 . . . substitute for y
3x +2 = 5 . . . . . . . simplify
3x = 3 . . . . . . . . . subtract 2
x = 1 . . . . . . . . . divide by 3
y = -8×1 +2 = -6 . . . . use the first equation to find y
The solution is (x, y) = (1, -6).
