Question

Simplify the expression

5(x-z) + 4(y-x)

I came up with 9(z+y) - (x2)

X to the second power by the way
I don't know if I'm correct or not

Answer 1

Would you mind typing in the procedure you used to obtain your 9(z+y)-x^2 result, please? Then I could give you better feedback.

Note: "the square of x" is written as x^2, not as x2.

Answer 2

5(x-z)=?

Answer 3

Ok thanks lol I didn't know how to type it

Answer 4

This is what I did, like I said I don't really know how to do it..
5(x-y) + 4(y-x) =
9 • (x-z) + (y-x) =
9(z+y - x^2)
