You would need 3 pails of plaster, specifically about 2 pails and a fifth of another but you cant buy a fraction of a pail, so 3 pails are needed.
4x-8=9x+2
4x=9x+10
-5x=10
5x=-10
x=-2
The first blank should be -5. The second should be -10. The third one should 10, if it’s talking about the opposite of -10.
