a a+b=20
The equation given is a+b=20. The question is asking to find the value of a.
To solve this equation, we can isolate the variable a by subtracting b from both sides of the equation. This will give us:
a + b - b = 20 - b
Simplifying the equation gives:
a = 20 - b
Now, since we already have the value of b, which is 20, we can substitute it into the equation:
a = 20 - 20
Simplifying further:
a = 0
Therefore, the value of a is 0.
