Answer» 10x + 10y - 2z is the solution. Step-by-step explanation: We have to subtract the SUM of 9x - 5y + 4Z and 6x+2y+3Z from the sum of 10x -3y+4z and 3x+6y-5z. (10x - 3y + 4z) + ( 3x + 6y - 5z) - (9x - 5y + 4z) + ( 6x + 2y + 3z) 10x + 3x - 9x + 6x = 10x [x terms] -3y +6y + 5y + 2y = 10y [y terms] 4z - 5z - 4z +3z = -2z [z terms] 10x + 10y - 2z is your answer |
