I came across the following question and as there are no values after an equals sign I am at a loss as to how to even begin to go about solving it.
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.
