Solve each system by multiplying. check ur answer.

Multiply all terms in the first equation by 2 and all terms in the second by 3.
You should obtain:

6x + 16y = 34
-6x + 27y = 9

       43y =43, and so y = 1.  Subbing 1 for y in the first eq'n, we get

3x + 8(1) = 17, or 3x = 9, or x = 3.

The solution is (3, 1).

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.
