what dose 3x-5y=15 and 2x-y=-4 really equel
The correct answer would be (-5,-6). Hope that helps!
3x - 5y = 15 -----> 1 2x - y = -4 ------>2 multiply eqn2 by -5 and add eqn 1 3x-5y = 15 -10x +5y = 20 ---------------------7x = 35 x = -5 sub in eqn 2 2(-5) - y = -4 -10 - y = -4 -y = -4+10 -y = 6 y = -6 so the answer is (-5, -6)
