I NEED TO SOLVE FOR Y AND X
im getting rele confused on this. ok here is the prob.

x+y=5
x-2y=-4

equation 1 x+y=5
equation 2 x-2y=-4

Multiply equation 1 by -1.
Add equation 1 to equation 2. The x term cancels. Solve for y.

THEN, put the value of y into either equation and solve for x.

Finally, put the value of x and y into the OTHER equation and see if those values satisfy the equation.
