2/(5 )=(x-2)/20

To solve the equation (2/5) = (x-2)/20, we can use cross multiplication.

Cross multiplication involves multiplying the numerator of the left side with the denominator of the right side, and vice versa.

Starting with the equation:

(2/5) = (x-2)/20

Cross multiplying, we have:

2 * 20 = 5 * (x-2)

40 = 5x - 10

To isolate the variable x, we need to get rid of the constant term (-10). To do this, we will add 10 to both sides of the equation:

40 + 10 = 5x - 10 + 10

50 = 5x

Now, to solve for x, we divide both sides of the equation by 5:

50/5 = 5x/5

10 = x

Therefore, the solution to the equation (2/5) = (x-2)/20 is x = 10.
