You want to get rid of one of the variables, so multiply the top equation by two and add them together.

12y=48, solve for y and plug it into one of the others to find the answer

anonymous · Answer

2x + 6y = 26
-2x + 6y = 22

12y = 48

y = 4

solve for x

2x +6(4) = 26
2x = 26 - 24
2x = 2 
x  = 1
