ALGEBRA 1!PLZ HELP!

Use the Substitution method to solve the system of equations.

y - 2x = -5
3y - x = 5

Solve the first equation for y.
y = 2x-5
Substitute that for y in the second equation and solve for x. Then use the value of x to substitute back into the first equation and solve for y. Post your work if you get stuck.

WOULD IT BE:
4Y-X=0?

y - 2x = -5 (equation 1)
3y - x = 5 (equation 2)
=============
Use equation 1 to solve for y as I did earlier.
y = 2x + 5
Now substitute that value of y (from equation 1) into equation 2.
equation 2 is
3y-x=5. Plug the value for y into this.
3(2x+5)-x=5
Now solve for x. Then use that value for x into equation 1 and solve for y.
Post your work if you get stuck. Not a "would it be" answer.

what is a possible point that lies on the graph

y=-2x-5
