Solve systems by substitution
 y = -24x - 3y = 18Substitute the appropriate expression into theother equation of this system.4x-3(       ) = 18 (y = -24x - 3y = 18solve the system of equations by substitution method,) 2x - 3y =  -1x = y + 12(              ) -3y= -1Substitute the appropriate expression into theother equation of this system. (2x - 3y =  -1x = y + 1solve the system of equations by substitution method,) y = 6x - 11-2x - 3y = -7-2x-3(           )=-7Substitute the appropriate expression into theother equation of this system. (y = 6x - 11-2x - 3y = -7solve the system of equations by substitution method,) y = -2x + 206x - 5y = 126x-5(           ) = 12Substitute the appropriate expression into theother equation of this system. (y = -2x + 206x - 5y = 12solve the system of equations by substitution method,) -3(            ) - 3y = -15x = -3y + 1-3x - 3y =  -15Substitute the appropriate expression into theother equation of this system. (x = -3y + 1-3x - 3y =  -15solve the system of equations by substitution method,)
