2. not 2. You want to eliminate the 'y' term. then you solve the resulting equation for x. and substitute that value back into either of the first equations to get a value for y.

7x+4y=4 (1) 5x+8y=28 (2) 14x8y=8 <= (1) * 2 = (3) 9x=36 <= (3) + (2) Solve for x: x=4 Now plug 4 into either (1) or (2) and solve for y.
