Look at my previous answers on types of questions like these.
Here is the first one to the equation stage. You can work it our from there...
Define 2 numbers to be x and y, so we know x+y = 18 --eqn1
Also --eqn2
From 1, x=18-y. Sub this into eqn2 to give . Expand this, simplify it and solve the quadratic equation to find y then find x from equation 1.
then try the second one yourself
