I need to estimate the coordinates of the point of intersection

of the two lines. The answer I need to give is to the nearest integer.

Does this mean to the nearest whole number i.e. zero decimal places?

yes ... no decimal places

ionk know how to do this

Yes, when you are asked to provide an answer to the nearest integer, it means you need to round the answer to the nearest whole number. In other words, you should not include any decimal places in the final answer.
