2x-y =3
multiply by 4
8x - 4y = 12
3x +4y = 10 (unchanged equation)
------------------add
11x = 22
answer is A. the first.
first equation multiplied by 4 then sum to get 11x = 22
A way to remember what you have learned is creating notes or doing practice problems
The answer is x=-16
2/3x-1/6x=-8 (combine like terms)
3/6x=-8
1/2x=-8
x=-16
Hope this helps
