Solve by elimination. Subtract the second equation from the first:
(-5x+4y) - (-5x-8y) = 48 - 24
4y + 8y = 24
12y = 24 ā y = 2.
Substitute into the first equation:
-5x + 4(2) = 48 ā -5x + 8 = 48 ā -5x = 40 ā x = -8.
Solution: (x,y) = (-8, 2).
(-5x+4y) - (-5x-8y) = 48 - 24
4y + 8y = 24
12y = 24 ā y = 2.
Substitute into the first equation:
-5x + 4(2) = 48 ā -5x + 8 = 48 ā -5x = 40 ā x = -8.
Solution: (x,y) = (-8, 2).
