Write an equation and solve for the unknown number. Twice a number, increased by 3 is 7. (1 point)

1 answer

Let's call the unknown number "x".

The equation to represent "Twice a number, increased by 3 is 7" would be:

2x + 3 = 7

To solve for the unknown number, we will isolate x:

2x + 3 - 3 = 7 - 3

2x = 4

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

2x/2 = 4/2

x = 2

Therefore, the unknown number is 2.
