If 12 less than 4 times a number is 8, the number is 5. Write a different sentence where the unknown number is also 5.

If 12 less than 4 times a number is 8, the number is 5. This sentence can be rewritten as 4x - 12 = 8 and x = 5. Another way to write the first equation is to divide both sides by either 2 or 4;

(4x-12)/(2)=(8)/(2)\\ 2x-6=4\\or\\ (4x-12)/(4)=(8)/(4)\\ x-3=2
So another equation you can use is x - 3 = 2 or 2x - 6 = 4.

basicly just plug in some nubers around the  five like 3 + 5 - 10 = - 2 or  3 + unkown number - 10 = -2
