Question

the solution to the system y=2x-3 is: 5x=2y=30

Answer 1

Do you have a question here?

Answer 2

I think he's asking what is the solution to that system of equation is that right?

Answer 3

yes ,that is right.

Answer 4

There are many methods to solve this but you can start by using substitution.
y=2x-3
Is the second equation 5x=2y-30? That = sign doesn't belong there?

Answer 5

yes

Answer 6

The first equation already gives you what y= to. It equals to 2x-3. You can just plug y=2x-3 into 5x=2y-30.
Your equation would then be 5x=(2(2x-3))-30
Now you should solve for x after simplifying
5x= 4x-6-30
5x=4x-36
Subtract 4x on both sides
x=-36
Plug x=-36 back into one of the equations above. For example, y=2x-3
2(-36)-3 = -75
That means your answer is (-36, -75) Plug those values into your equation and they should both work.
