Question

Solve for w
10/w-4 = 5/4
Simplify your answer as much as possible.

Answer 1

Answer: w=12

Explanation:

`\displaystyle\\(10)/(w-4) =(5)/(4)\\\\(10)/(w-4) =((5)(2))/((4)(2))\\\\(10)/(w-4)=(10)/(8) \\`

If the numerators of fractions are equal, their denominators are also equal.

Hence:

w-4=8

w-4+4=8+4

w=12

Answer 2

w = 40/21 (1 and 19/21)
