2x*x=2x^2
2x*-y=-2xy
3y*x=3yx
3y*-y=3
2*x=2x
2*-y=-2y
-3x*x=-3
-3x*-y=3xy
combine like terms and that is your answer
There are many solutions. infinite solutions at that. when you solve it it equals itself 2.5w+21= 2.5w+21 so that means all numbers would work as a solution.
The answer would be (-y, x).
Hope this helps.
Thw answer would be 0.007
I think it is 6 (Would be 6/9)
4/5 - ?/9 = 6/45
Make the denominators the same
4/5 (9/9) = 36/45
?/9 (5/5) = ?/45
To get the number, you take 6 from 36 to get 30. And to check, 36-30=6.
Now the fraction is 30/45 and you divide both numbers by 5 to get back to the previous number which would be 45/5 = 9 and 30/5 = 6 which gets you 6/9
