What is twelve less than a variable
​

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.

x - 12

Step-by-step explanation:

"twelve" - number

"less than" - switches the entire expression

"a variable" - a unknown number shown as a letter. can be x.

Now we have cut the entire word expression into smaller peices, we can combine it into a actual expression.

12 - x will turn into:

x - 12

Hope this helped.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
