Answer:

1 1/9

Explanation:

To solve this equation, we need to isolate the variable on one side of the equation.

First, we can distribute the "15-7" on the right side of the equation to get:

12 less than two times a number is equal to 15 - 7*number

Then, we can combine the two constants on the right side of the equation to get:

12 less than two times a number is equal to 8 - 7*number

Next, we can add 12 to both sides of the equation to get:

2number is equal to 20 - 7number

Then, we can combine the two terms on the right side of the equation to get:

2number is equal to 13 - 7number

Finally, we can add 7*number to both sides of the equation to get:

9*number is equal to 13

Dividing both sides of the equation by 9, we get:

number is equal to 13/9

Simplifying, we get:

number is equal to 1 1/9

So the value of the number that satisfies the equation is 1 1/9.
