im getting rele confused on this. ok here is the prob.

x+y=5

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.
