# Solve the system of equations

5/4x - 4/3y + 5/4z = 6 5/16x + 5/4y - 4/16z = -4 3/4x - y +3/4z = 6

# Solve the system of equations

x-3y+4z=13 2x+y+z=-2 -2x+3y-3z=-10

# solving systems of equations 5x - 2y = -24

Did I solve these correctly?   1.  5x - 2y = -24          -  4y = -48 - 10x   =   5x - 2y = -24   ...
