Solve Systems by Substitution
 y = -24x - 3y = 18Substitute the appropriate expression into theother equation of this system.4x-3(      ) = 18 (The first step is shown.Solve the system of equations by substitution. y = -24x - 3y = 184x - 3(-2) = 18,) 2(          ) -3y= -1Substitute the appropriate expression into theother equation of this system.2x - 3y =  -1x = y + 1 (The first step is shown.Solve the system of equations using substitution.2(y + 1) - 3y= -12x - 3y =  -1x = y + 1,) Substitute the appropriate expression into theother equation of this system.-2x-3(         )=-7y = 6x - 11-2x - 3y = -7 (The first step is shown.-2x - 3(6x - 11) = -7Solve the system of equations using substitution.y = 6x - 11-2x - 3y = -7,) 6x-5(           ) = 12y = -2x + 206x - 5y = 12Substitute the appropriate expression into theother equation of this system. (The first step is shown.y = -2x + 206x - 5y = 126x - 5(-2x + 20) = 12Solve the system of equations using substitution.,) -3(         ) - 3y = -15Substitute the appropriate expression into theother equation of this system.x = -3y + 1-3x - 3y =  -15 (-3(-3y + 1) - 3y = -15The first step is shown.Solve the system of equations using substitution.x = -3y + 1-3x - 3y =  -15,)
