Question

Математика: 9n-(8+5n)= m+(2m-3)= -(4x+3y)-(-8x+7y)= 1,5(2x-3)= -(8z+1)+5(4z-3)= a(10b+9)-a(b-1)=

yashinaalyona20 · Answer

9n-(8+5n)=9n-8-5n=4n-8=4(n-2)m+(2m-3)=m+2m-3=3m-3=3(m-1)-(4x+3y)-(-8x+7y)=-4x-3y+8x-7y=4x-10y1,5(2x-3)=3x-4,5-(8z+1)+5(4z-3)=-8z-1+20z-15=12z-16=4(3z-4)a(10b+9)-a(b-1)=10ab+9a-ab+a=9ab+10aПошаговое объяснение:...

9n-(8+5n)= m+(2m-3)= -(4x+3y)-(-8x+7y)= 1,5(2x-3)= -(8z+1)+5(4z-3)= a(10b+9)-a(b-1)=
