Answer:
( 1 , 1 )
Step-by-step explanation:
2x + y = 3
x = 2y - 1
(You already have x so substitute x back into 2x + y = 3)
2(2y - 1) + y = 3
4y - 2 + y = 3
5y - 2 = 3
(Add -2 to both sides)
5y = 5
(Divide each side by 5 to isolate x)
y = 1
(Plug y into x = 2y - 1 to find x)
x = 2(1) - 1
x = 2 - 1
x = 1
