Question

A. Step 1B. Step 2C. Step 3D. Olga did not make a mistake

Answer 1

The equation given is:

`(1)/(4)((1)/(3)k+9)=6`

Multiply both-side of the equation by 6

`4*(1)/(4)((1)/(3)k+9)=6*4`
`((1)/(3)k+9)=24`

subtract 9 from both-side of the equation

`(1)/(3)k=15`

To get k, we are to multiply both-side of the equation

`k=45`

Therefore, Olga made a mistake in the last step
