Question 291929: What is the answer if you solve each system of equation by substitution?
4y+3x=-3
y=5x-5 Found 2 solutions by richwmiller, stanbon:Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! 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.
No more than 4 submissions daily. [4 problems a day]
No similar problems. [Different type problems only.]

4y+3x=-3
y=5x-5
---------------------------
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
