Solve the system by either elimination or substitution 3x-5y=21 2x+y=1 a.2,-3 b.2,3 c.-2,-1 d.-2,1 my guess is c

The correct answer is A: x=2 and y=-3. Either method would work, but for example, let's use elimination. If you multiply the second equation by 5, you get: 10x +5y = 5. When you add both equations, you can then cross out both y terms. You are left with one equation that reads: 13x=26. Solving for x gives you 2. You can substitute 2 in for x in either equation and you will receive -3 for your y value.
