Question

What is the value of y in the solution to the following system of equations?
5x - 3y = -3
2x - 6y = -6

A) -1
B) 0
C) 1
D) 2

Answer 1

y=1 so C

Answer 2

can i ask how you did this? @jcoolcat29

Answer 3

2x - 6y = -6
2x = -6 + 6y
x = -3 +3y

Plug that answer into the other equation

5(-3 +3y) -3y = -3
-15 + 15y -3y = -3
12y = 12
y = 1

Does that make sense

Answer 4

oh yeah yeah yeah ok i get that @jcoolcat29
