The sum of twice a number and 4 less than the number is the same as the difference between -32 and the number. What is the number?

Answer 1

Let the number be x:
2x - 4 = x + 32
x =32 + 4
x = 36

Answer 2

Note that x + 32 is because x -(-32) = x + 32

Answer 3

let the number be X
2X+ ( X-4)=X+32
3X-4=X+32
2X=36
X=18
