SUMMARY

The discussion centers on solving the equation 2x = 12 - x, where x represents an unknown number. The equation is derived from the statement that the product of 2 and the number equals 12 minus the number. To isolate x, one must add x to both sides, resulting in 3x = 12. Dividing both sides by 3 yields the solution x = 4.

The product of 2 and a number is the same as 12 subtract the number. Find the number.

If you could please help me with this, thank you.

Call that number "x". Then "the product of 2 and a number" is 2x. "12 subtract the number" is 12- x. They are the same: 2x= 12- x.

To solve for x, start by adding x to both sides. What do you get?
