Question

Four times the sum of a number and -3 is 7 more than quadruple the number. What’s the equation?

Answer 1

Let the unknown number be x.

4(x + (-3)) = 7 + 4x

4x - 12 = 7 + 4x.

-12 ≠ 7

There is no equation cause this is cannot happen.

Answer 2

4(n+-3)=7+4n
The answer is really 
4(n-3)=7+4n
