It is possible but there is no method in junior cert maths that you can use to solve this. You are probably expected to use a graph to estimate the solution

Show me how it possible then, or don't say it JackW ( This may be coming across as rude but I genuinely want to know this method not on the junior cert).

This is a simultaneous equation-a father and his son have a combined age of 52.8 years ago the father was 8 times the sons age .write and equation in x and y
