Twelve less then x

Question

Twelve less then x is equal to 51. What is the equation and then the solution

Answer 1

First let x equal the unknown variable. Next it says 12 less than x, so write x-12 and set that equal to 51. The equation is : x-12= 51. To solve: The opposite of subtracting is adding, so 12 is added to both sides. This will mean on the left side -12+12 =0 so that the left is just x alone. On the right, it becomes 51+12 = 63. So then you have: x=63 and that is the final answer. If you don’t understand any part of this solution, let me know.

Answer 2

Equation: x - 12 = 51

Add 12 to both sides of our equation to isolate x:

Solution: x = 63
