Answer:
a) 5x^2-3x^2+7x^2-2x^2= 7x^2
b) 5x^2-3x^2-5x^2+2xy+3xy= -3x^2+5xy
c) 8x-9y+2z+(-6x+7y-5z)+(-3x-8y+6z)= 8x-9y+2z-6x+7y-5z-3x-8y+6z= -x-10y+3z
d) 3x^2-2x+5+(-5x^2+3x-2)= 3x^2-2x+5-5x^2+3x-2= -2x^2+x+3
Step-by-step explanation
Because you have to add same variable terms like 5xy+3x+3xy+6x+7y+8z+6y+4z= 5xy+3xy+3x+6x+7y+6y+8z+4z= 8xy+9x+13y+12z
Hope you have understand what I am trying to say
Variables means alphabets like x, y, z which is attached with constant.
