# Q. 3.     Pick out the solution from the values given in the bracket next to each equation. Show that the other values do not satisfy the equation.            (a)                                 (b)                           (c)                               (d)                                        (e)                              (f)

(a)

Putting given values in LHS.

m = 10 is not a solution.                             m = 12 is a solution.

m = 5 is not a solution.                              m = 15 is not a solution.

(b)

Putting given values in LHS.

n = 12 is not a solution.                                n = 20 is not a solution.

n = 8  is  a solution.                                      n  =0  is not a solution.

(c)

Putting given values in LHS.

p =0 is not a solution.                                p = 10 is a solution.

p = 5 is not  a solution.                              p = -5 is not a solution

(d)

Putting given values in LHS.

q =7 is not a solution.                                q = 2 is not a solution.

q = 10 is not  a solution.                              q = 14 is a solution.

(e)

Putting given values in LHS.

r =4  is a solution.                                r = -4 is not  a solution.

r = 8 is not  a solution.                              r = 0 is not a solution

(f)

Putting given values in LHS.

x = -2 is a solution.                                 x = 0 is a solution.

x = 2 is not  a solution.                               x = 4 is not a solution
