Question

find f if 18= 734 + 20f / 44+ f​

Answer 1

Answer:

f=-42.8

Step-by-step explanation:

$18 = 734 + \frac{20f}{44 + f } \\ 18 - 734 = \frac{20f}{44 + f} \\( - 716)(44 + f )= 20f \\ - 31504 - 716f = 20 f \\ - 31504 = 20f + 716f \\ - 31504 = 736f \\ \frac{ - 31504}{736} = f \\ f = - 42.8(approx)$
