Question

10Cr=20Cr+1 find the value of r.

Answer 1

Now we have,,,,, 10Cr=20Cr+1
then, 10Cr-20Cr=1
then,-10Cr=1
so,r=-1/10C..

Answer 2

The value of r that satisfies the equation 10Cr = 20Cr + 1 is -1/10.

To solve for the value of r, we need to isolate it on one side of the equation.

We can do this by first subtracting 20Cr from both sides of the equation:

10Cr - 20Cr = 1

Next, we can simplify the left side of the equation by factoring out Cr:

Cr(10 - 20) = 1

Simplifying further:

-10Cr = 1

Finally, we can solve for Cr by dividing both sides of the equation by -10:

Cr = -1/10

Therefore, the value of r that satisfies the equation 10Cr = 20Cr + 1 is -1/10.
