Question

Che
10) Solve for X and check.
-X+
17
=
x - 4​

Answer 1

-x + 17 = x - 4 ——— subtract 17 on both sides
-x+17=x-4
-17 -17—— the 17’s cancel out and -4-17= -21
Now you’re left with...

-x=x -21 —-subtract x on both sides..
-x -x —-the x’s cancel out each other

And now it’s...
-2x=-21 —-divide -2 on both sides.. and now you’re left with...

x = 21/2

To check all you have to do it plug the x in the equation. I hope that helped

Answer 2

Explanation:

-x + 17 = x - 4

17 + 4 = x + x

2x = 21

x = 21/2
