Answer:
x = 2, y = 9
Step-by-step explanation:
y = 7x - 5
2x + y = 13
These equations can both be set to equal y.
y = 7x - 5
y = -2x + 13
Now that they both equal y, you can set them equal to each other.
7x - 5 = -2x + 13
add 2x to both sides
9x - 5 = 13
add 5 to both sides
9x = 18
divide by 9
x = 2
plug x into either equation
y = 7(2) - 5
y = 14 - 5
y = 9
2(2) + y = 13
4 + y = 13
y = 9
