6 + 21 = 27 (Add six ones)
60 + 21 = 81 (Add six tens)
I hope this helps:)
I'm sorry if it doesn't:(
Part A:
We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.
Part B:
As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.
So you need to know 32 centimeters in what?
