Solve the following system of equations. - 7x-4y=14 - 8x+5y=16

Answer: x=-2 and y=0

Step-by-step explanation: Add 4y to both sides, then divide both sides by - 7 to get x alone. X=-4/7y-2. Then substitute that in for x in the second part of the problem. - 8 (-4/7y-2) + 5y=16. Distribute to get 67/7y+16=16 and then subtract 16 from both sides. Divide 67/7y by 67/7, so y=0. Substitute y=0 back in so x=-4/7 (0) - 2 so x=-2.
