Let's denote the unknown number as x. The equation can be written as follows:
2x + 3 = 7
To solve for x, we first subtract 3 from both sides of the equation:
2x = 7 - 3
2x = 4
Now, we divide both sides of the equation by 2 to isolate the variable x:
x = 4/2
x = 2
Therefore, the unknown number is x = 2.
2x + 3 = 7
To solve for x, we first subtract 3 from both sides of the equation:
2x = 7 - 3
2x = 4
Now, we divide both sides of the equation by 2 to isolate the variable x:
x = 4/2
x = 2
Therefore, the unknown number is x = 2.
