Question

To solve this system using the addition method, you would need to multiply the first equation by what number in order for the x's to add out?
2x + 3y = 8

-6x + 4y = 11

Answer 1

1st equation should be multiplied with 3 
6x+9y=24
-6x+4y=11
________
13y=35
y=35/13 

2x+3y=8...1
put y=35/13 in 1
2x+3(35/13)=8
26x+105=104
26x=-1
x=-1/26
