Elise says, "If you subtract 14 from my number and multiply the difference by - 3, the result is - 63."
Ksivusya [100]
Answer:
35

Explanation:
Let x be equal to Elise’s number.
We can set up our equation like this:

(x-14)(-3)=-63
Expand the parentheses
-3x+42=-63
Subtract both sides by 42
-3x+42-42=-63-42
-3x=-105
Divide both sides by -3
-3x/-3=-105/-3
x=35

I hope this helps!
