Algebra ->  Linear-equations -> SOLUTION: x + y =5 2x - y =4 -2x +-2y = -10 2x-y =4 2x - y = 4 2x -2 =4 3y -6 __ ___ 3 = 3 y = -2 __ then lost - is this right so far a      Log On


   

Question 241386: x + y =5
2x - y =4
-2x +-2y = -10 2x-y =4
2x - y = 4 2x -2 =4

3y -6
__ ___
3 = 3

y = -2 __

then lost - is this right so far and can you show me how to do problem?

You can put this solution on YOUR website!
x + y =5
2x - y =4
.
x=5-y
2(5-y)-y=4 Replace x with 5-y.
10-2y-y=4
-3y=-6
y=2
x=3
.
