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.
p − 5 = 5 (0, 10, 5, − 5)
उत्तर
p − 5 = 5
p = 10 is a solution to the given equation because for p = 10,
p − 5 = 10 − 5 = 5 and hence, the equation is satisfied.
p = 0 is not a solution to the given equation because for p = 0,
p − 5 = 0 − 5 = −5 and not 5
p = 5 is not a solution to the given equation because for p = 5,
p − 5 = 5 − 5 = 0 and not 5
p = −5 is not a solution to the given equation because for p = −5,
p − 5 = − 5 − 5 = −10 and not 5
