Question

please help! MEDAL REWARDED!!!
What is the value of y in the solution to the following system of equations?

5x − 3y = −3
2x − 6y = −6

Answer 1

2x - 6y = -6 reduces to x - 3y = -3

now we have :
5x - 3y = -3
x - 3y = -3 --->(-5)
------------------
5x - 3y = -3
-5x + 15y = 15 (result of multiply by -5)
-------------------add
12y = 12
y = 1

This problem could have been solved without reducing the equation.....I just like messing with smaller numbers rather then bigger ones
