If x = a, y = b is the solution of the pair of equation x-y = 2 and x+y = 4 then what will be value of a and b a.2,1 b.3,1 c.4,6 d.1,2
Question
Solution 1
To find the values of a and b, we need to solve the system of equations given. The system of equations is:
x - y = 2 x + y = 4
We can solve this system of equations by adding the two equations together. This will eliminate y:
x - y + x + y = 2 + 4 2x = 6 x = 6 / 2 x = 3
So, a = 3.
