Question

When a number is subtracted from 25, the difference is 8 less than twice

that number. What is the number?

Answer 1

11

Explanation:

first, we would set up an equation. since they say that a number is subtracted from 25, let x represent that number and say 25-x. on the other side of the equation, since it says the difference would be 8 less than twice that number, we would say 2x-8 because twice x would be 2x and we'd subtract 8 from that.

the equation would look like this:

25-x=2x-8

next, we would solve. first get the x to one side of the equation:

25=3x-8

then, get the 3x by itself:

33=3x

finally, solve for x by dividing both sides of the equation by 3:

11=x

x=11.

The number is 11.
