The question is:

the lengths of the sides of an equilateral triangle are:

3(x+y) cm

(5x+2y-1) cm

5(x+1)cm

I expanded the brackets and combined like terms as, if the triangle is equilateral then all sides must be equal, but as there is no numerical value - e.g. = 12 - I cannot see how to find a numerical value for either x or y.
