In order to eliminate the y terms, the y terms must be reciprocals.
The first equation has 9y.
To eliminate y, you need to add to it -9y.
The second equation has y. In order for the second equation to have -9y, you must multiply both sides of the second equation by -9.

The statement is false. The only shape with fo it lines of symmetry is a square
22 quarters= $5.50
10 dimes= $1.00
