Answer:
x = 6
Step-by-step explanation:
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.
3D + 12
3(D) + 3(4)
3(D + 4)
9 x 5 x 3 would be the equation and the answer to the equation would be 45 x 3 which is 135. The answer to your question is 145 unit cubes.
Answer:
The correct answer will be 16 1/2 or 16.5
