Question

Solve the system using elimination.
2x+6y=-12
5x-5y=10

Answer 1

I will let @AbhimanyuPudi answer, i gotta go, if anything is wrong i shall correct when i return <3

Answer 2

2x+6y=-12
2x=-12-6y
x=-6-3y
Substitute this value of x in the second equation,
5x-5y=10
5(-6-3y)-5y=10
-30-15y-5y=10
y=-2
Substituite y=-2 in any of the equation to find x..I'll substitute it in second equation
5x-5y=10
5x-5(-2)=10
5x+10=10
5x=10-10
5x=0
x=0
So, x=0 and y=-2

Answer 3

Omg. Thanks soooo much!

Answer 4

welcome:)

Answer 5

wanna help with some more??(:

Answer 6

sure

Answer 7

that was the substitution method not elimination...

Answer 8

ya....elimination is like this:
multiply the first equation with 5 and the second equation with 2, you have
10x+30y= -60 and 10x-10y=20
Subtract the second one from the first,
10x+30y-10x+10y= -60-20
40y= -80
y= -2
Substitute this value in any of the given equations and you get the value of x
x=0
