Question

X-8/15x=4 1/5 решить уровнение

Answer 1

===========================================

Answer 2

To solve the equation X - 8/15X = 4 1/5, we need to first simplify the mixed number 4 1/5 to an improper fraction:

4 1/5 = (4 x 5 + 1)/5 = 21/5

Now we can rewrite the equation as:

7/15X = 21/5

To isolate X, we can multiply both sides by the reciprocal of 7/15:

X = (21/5) / (7/15)

To divide by a fraction, we can invert and multiply:

X = (21/5) * (15/7) = 63/7 = 9

Therefore, the solution to the equation X - 8/15X = 4 1/5 is X = 9.
