Let's call the number x. The equation can be written as:
2x + 3 = 7
Now we'll solve for x:
Subtract 3 from both sides of the equation:
2x + 3 - 3 = 7 - 3
This simplifies to:
2x = 4
To isolate x, we divide both sides of the equation by 2:
2x/2 = 4/2
This simplifies to:
x = 2
So the number is 2.
2x + 3 = 7
Now we'll solve for x:
Subtract 3 from both sides of the equation:
2x + 3 - 3 = 7 - 3
This simplifies to:
2x = 4
To isolate x, we divide both sides of the equation by 2:
2x/2 = 4/2
This simplifies to:
x = 2
So the number is 2.
