4/7 = 8/5x-2

1 answer

To solve the equation 4/7 = 8/(5x-2), we can start by cross multiplying:

4(5x-2) = 8(7)

Simplifying both sides:

20x - 8 = 56

Now, isolate the term with x:

20x = 56 + 8
20x = 64

Divide by 20 on both sides:

x = 64/20
x = 3.2

Therefore, the solution to the equation is x = 3.2.
