If both a and b are positive integers, then from the following equations we have to find the value of 'a'.
1) 2a + b = 22
2) 34 - 2b = 10
Now, read the following options and select whichever option is applicable.
1
Equation 1 alone is sufficient to find the value of 'a'.
2
Only equation 2 is sufficient to find the value of 'a'.
3
Neither Equation 1 alone nor Equation 2 alone is sufficient to find the value of 'a', but both are necessary together.
4
The value of 'a' cannot be determined from any one equation. Even the two equations cannot be known jointly.
