Question

a) (4x-3y+13)+(7x+8y-6)+(2y-5-8x)=
b) (5x-3y+1)+(2y-x-7)+(12+6y-15x)=
c) (a+10b-g)+(3a-5b+4c)+(2c+b-6)=
d) (8xy-2yz)+(2xy-z+6yz)+(9yz-7yz-3z)=

Answer 1

a)4x-3y+13+7x+8y-6+2y-5-8x = 3x+7y+2
b)5x-3y+1+2y-x-7+12+6y-15x = -11x+5y+6
c)a+10b-g+3a-5b+4c+2c+b-6 = 4a+6b-g+6c-6
d)8xy-2yz+2xy-z+6yz+9yz-7yz-3z = 10xy+6yz-4z
