Answer:
x = 4
y = 3
Explanation:
First, reorder the first equation to make it into the same format as the second equation:
y = 2x - 5
-2x + y = -5
Then, put the equations together:
-2x + y = -5
x + y = 7
Solve by elimination by multiplying the bottom equation by 2, then add the equations together and solve for y:
-2x + y = -5
2x + 2y = 14
3y = 9
y = 3
Then, plug in 3 as y into one of the equations to solve for x:
y = 2x - 5
3 = 2x - 5
8 = 2x
4 = x
So, the answer is x = 4 and y = 3
