twice a number increased by 3 is 7, what is the number

Answer 1

Let's represent the number as "x". According to the given information, twice the number increased by 3 can be expressed as 2x + 3.

Now we can set up an equation based on the given information:

2x + 3 = 7

To isolate "x", we subtract 3 from both sides of the equation:

2x + 3 - 3 = 7 - 3
2x = 4

Then, we divide both sides of the equation by 2 to solve for "x":

2x/2 = 4/2
x = 2

Therefore, the number is 2.
