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.
