Use a calculator to find an approximate solution to the equation. Round any intermediate work and steps to three decimal places. 2ln(x+2.8)=3.2

    well this is a guess and check method... so let x = 10 substitute it and then calculate the value... that's how it appears you are being asked to get a solution. If the value of 10 doesn't work, then put a larger or smaller value in. and then keep adjusting till you get an answer

    seems to make sense to me... but you need to refine the value of x as they ask for 3 decimal places... at the moment you have 1

    well I think you are still a little high... look at x = 2.153 and then see what you get
