2/5w =40 solve the equation and check the solution

This is a linear equation.

To solve a linear equation we shall use the reverse operation.

Here we have

Which means times w.

The reverse operation of times is division.

For a fraction we may multiply by the flip fraction. Here we shall multiply both sides by 5/2

We get

Multiplying both sides by 5/2, we get

Simplifying we get

Now to verify, let us substitute 100 in the left side to see if we get 40 as the answer

Hence the value of w = 100
