Question

Show that 9.1 is not a solution of the equation n-6.4 = 2.61. Then find
the solution

Answer 1

The solution is 9.01.

Explanation:

To prove that 9.1 isn't the solution we have to plug 9.1 into the equation. By replacing n with 9.1 we get 2.7 which isn't equal to 2.61.

To find the solution we must add 6.4 to both sides of the equation.
