Answers & Comments
Answer:
1. (6y+3)+(10y+6)= 16y+9
6y + 10y = 16y
3+6=9
2.(3x²+4x)+(5x²-2x)= 8x²+2x
3x²+5x²=8x²
4x-2x=+2x
3.(3x²+5x-6)+(4x²-3x+10)= 7x²+2x+4
3x²+4x²= 7x²
5x-3x= +2x
-6+10= +4
4.(10x+3y-5)+(-12x-5y-10)= -2x-2y-15
10x-12x= -2x
3y-5y= -2y
-5-10= -15
5.(7y³-10x+3)+(3x²+3x-4)= 10x³-7x-1
7y³+3x²= 10x³
-10x+3x= -7x
3-4= -1
6.(10x²y+3xy+2x)+(-5x²y-2xy+15x)= 5x²y+1xy+17x
10x²y-5x²y= 5x²y
3xy-2xy= 1xy
2x+15x= 17x
