Question

Find X and Y X - 3 y + 3 15 12

Answer 1

To solve this problem we have to remember that diagonals of a parallelogram bisect each other. This means that they intersect in the midle point of each other. From this we can conclude that

`\begin{gathered} x-3=15 \\ \text{and} \\ y+3=12 \end{gathered}`

Once we have our equations we can solve them. Let's find x

`\begin{gathered} x-3=15 \\ x=15+3 \\ x=18 \end{gathered}`

Now, let's find y

`\begin{gathered} y+3=12 \\ y=12-3 \\ y=9 \end{gathered}`

Then x=18 and y=9,
