The given equation is expressed as
5/7 = 4x/83
To find the value of x, we would crossmultiply. Thus, we have
5 * 83 = 4x * 7
415 = 28x
28x = 415
Dividing both sides of the equation by 28, it becomes
28x/28 = 415/28
x = 415/28
Converting to mixed number, the number of times that 415 would divide 28 without a remainder is 14. This forms the whole number. The remainder is 23. Thus, the mixed number would be
x = 14 23/28
