Question

needs help solving systems of equations
y=4x+45 GIVING MEDALS
x=4y

Answer 1

So, you know in your second equation, you directly have x = 4y
and you have a 4x term in the first equation

So... you can substitute in "4y" in the first equation where x is

y = 4(4y) + 45

Now essentially you have just one equation with 1 variable y which should be (hopefully) easy to solve

Answer 2

Once you find the value of y by solving y = 4(4y) + 45, you can use that value of y in the equation below [x = 4y], to find the value of x!
