You <em>multiply</em> both sides of the first equation by  4.
Then you have . . .
                            -2x + 4y  =  3     and     y - 2x  = 3 .

If you want to get rid of a fraction, you multiply it by itsdenominator.
BUT ... whatever you do to one term on one side of the equation, you
have to do the same to <em>all</em> the terms on that side, AND then you have to
do the same thing to all the termson the OTHER side.

D.2<br> Geometry math question no Guessing
AnnyKZ [126]
C. 3

The shape can fit on to itself 3 times before returning to its original position.

Next time try this:

1. Trace and cut out the shape
2. Label the top 'A'
3. Trace the shape one more time. DO NOT CUT THIS ONE OUT
4. Put the cut out shape on the 2nd traced one
5. Put a pen in on the point, like a spinner, and rotate it 90degrees
6. See how many it can fit into itself before 'A' returns to the top.

That will be your answer.
