Let's assume the unknown number is "x".
The equation for the given problem can be written as:
2x + 3 = 7
To solve for the unknown number, we need to isolate the variable "x" on one side of the equation.
Subtracting 3 from both sides:
2x + 3 - 3 = 7 - 3
Simplifying:
2x = 4
Finally, dividing both sides by 2:
2x/2 = 4/2
Simplifying again:
x = 2
So, the unknown number is 2.
