what number = x

x - 3.5 = 12.7

Isolate the x, add 3.5 from both sides

x - 3.5 (+3.5) = 12.7 (+3.5)

x = 12.7 (+3.5)

x = 16.2

16.2 is your answer

Let's make an equation. We need to find a number that when 3.5 is subtraced from it is 12.7. The equation would look like.
X-3.5=12.7
Now, we need X by itself, so we need to add 3.5 to both sides.
X=12.7+3.5
X=16.2
If the number is 16.2, let's check.
16.2-3.5=12.7
The number is 16.2.
