Here are the equations: 1/2x+1/3y=-4 1/5x+1/5y=-2 Can someone solve this using the elimination method? Ty!!
Whenever I try to solve this I get 0=0. I don't know what that means or if that's correct. Please help.
Substitution Form: 2x-3y=2 x+y=-1 x+y=-1 Elimination From: 2x/3 - 4y/5 = 1 and 3x-y=-7
4x+3y=15 8x+9y=15
Substitution Form: 2x-3y=2 x+y=-1 x+y=-1 Elimination Form: 2x/3 - 4y/5 = 1 and 3x-y=-7

5x-1 / 3 + y+7 / 4 = 11 x+1/2 - x-y/3=3 Find the solution set The 5x-1 is over 3, the y+7 is over 4 x+1 is over 2, x-y is over 3
Solve the system. State whether the system is inconsistent or has infinitely many solutions. If the system has infinitely many solutions, write the solution set with y arbitrary. 4...
