Question
Using variables a and b write any two equations whose solution is (0, 2).
Solution
a + b = 2 and 2a + b = 2 are the equations whose solution is (0, 2).
Reason:
a + b = 2 ...(i)
2a + b = 2 ...(ii)
Subtracting equation (i) from (ii), we get
2a + b = 2
a + b = 2
− − −
a = 0
Substituting a = 0 in equation (i), we get
0 + b = 2
∴ b = 2
