Question 410763: I am totally lost please help. Solving by substitution or elimination
2x+y=6
x-y=3
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
Basic outline:
Add the two equations to get:
2x+y=6
x-y=3
------
3x+0y=9
which gives us the new equation 3x=9
Next solve for x. Once you have the solution for x, use it to find y. You do this by plugging that value of x into either equation and solving for y.
