Question

Three more than twice a number is equal to four less than the number. Find the number.

Answer 1

Let $x$ be the number

So, three more than twice the number is

$2x+3$

four less than the number is $x-4$

Since these are equal, we can say:

$2x+3=x-4$

$2x-x=-4-3$

$x=-7$

Hence, this is the answer.
