A) 4(2y-7y*2)-3(y*2-3y) = 8y - 28y*2 - 3y*2 + 9y = 17y - 31y*2
b) -5(2b+3z)+2(2b-4z) = -10b - 15z + 4b - 8z = -6b - 7z

A)4(2y-7y*2)-3(y*2-3y)=8y-28y*2-3y*2-9y=-y-31y*2
b)-5(2b+3z)+2(2b-4z)=-10b-15z+4b-8z=-6b-23z

A.) 4(2y-7y*2)-3(y*2-3y)= 8y-28y*2-3y*2+9y=17y-31y*2
b.)-5(2b+3z)+2(2b-4z) =-10b-15z+4b-8z=6b-23z
