Answer:
(2,3)
Step-by-step explanation:
4x - y = 5
4x - 5 = y
8x - 5y = 1
8x - 5(4x - 5) = 1
8x - 20x + 25 = 1
8x - 20x = 1 - 25
-12x = - 24
x = -24/-12
x = 2
y = 4x - 5
y = 4(2) - 5
y = 8 - 5
y = 3
check...
4x - y = 5
4(2) - 3 = 5
8 - 3 = 5
5 = 5 (correct)...so it checks out
solution is : x = 2 and y = 3...or (2,3)
