The answer is B 90 percent
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.
I think it’s either b or c

If a term doesn't have an exponent, its implied exponent is 1

Multiply the terms with the same base by adding their exponents
