Simplify the following expression. 2x − 2y − 5z + 2x + 2y + 3z 4x − 4y − 2z 4x − 4y − 8z 4x − 4y + 8z 4x − 2z
2x-2y-5z+2x+2y+3z Since 2x and 2x are like terms, add 2x to 2x to get 4x. 4x-2y-5z+2y+3z Since -2y and 2y are like terms, subtract 2y from -2y to get 0. 4x-5z+3z Since -5z and 3z are like terms, subtract 3z from -5z to get -2z. 4x-2z
you have to combine like term and reeber to add and s tract accrording to the sign
thank you so much!!
