The method (substitution or elimination) I use should not change the answer.
4*(5x-5)+3x=-3
solve for x
Some website rules you won't like:
You are limited to one problem per submission. [One problem at a time.]
To be sure we understand each other, one means one not two or three or more.

---------------------------
Substitute for "y" and solve for "x":
4(5x-5)+3x = -3
20x-20+3x = -3
23x = 17
x = 17/23
------------------------------
Substitute for "x" and solve for "y":
y = 5(17/23)-5
y = 85/23 - 115/23
y = 200/23
