Question

original problem
x + y = 5
x = 4y

x =4y
x +y = 5
(4y) + y =5 because we substitute 4y for x
Then add 4y and y
5y = 5
Divide both sides by 5 to get the y alone
5y/5 = 5/5
5/5=1
y=1

Then i put in the second equation
x=4(1)
4x1=4

so x=4
and y =1

i need checksteps for both problems please

Answer 1

so you need to check to see if x=4 and y=1, is that correct?

Answer 2

yes it is the solution
