Answer 1

Answer:

(a) 12x-9=3(4x-3).

12x-9=12x-9.

12x-12x=-9+9.

0=0. (Because 12x-12x will cancel & -9+9 will also cancel).

(b) -25y-35=-5(5y+7).

-25y-35=-25y-35. (Because -×+=-).

-25y+25y=-35+35.

0=0. (Because -25y+25y will cancel & -35+35 will also cancel).

(c) 27b-36by=9b(3-4y).

27b-36by=27b-36by.

27b-27b=-36by+36by.

0=0. (Because 27b-27b will cancel & -36by+36by will also cancel).

(d) 8ax+12a-4az=4a(2x+3-z).

8ax+12a-4az=8ax+12a-4az.

8ax-8ax=+12a-12a=-4az+4az.

0=0=0. (Because 8ax-8ax will cancel, +12a-12a will also cancel & -4az+4az will also be cancelled).

(e) 4m-6my-18mz=2m(2-3y-9z).

4m-6my-18mz=4m-6my-18mz.

4m-4m=-6my+6my=-18mz+18mz.

0=0=0. (Because 4m-4m will cancel, -6my+6my will also cancel & -18mz+18mz will also be cancelled).

I think this is your answer.
