First solve for one variable
(I chose bottom equation because it’s easier)
Get y alone: Y = 5x
Now that we have y we can plug y into the top equation
Plug in 5x for y: 2x + 5x = 7
Solve for x: 7x = 7
X = 1

Now plug in the x value into the bottom equation to solve for y
Y = 5(1)
Y= 5


So, x = 1 and y = 5
