Answer:
B
Step-by-step explanation:
Answer:
19 and 20
Step-by-step explanation:
Let x be the larger number
x - 1 + x = 4x - 41
We can combine like terms and isolate x:
2x - 1 = 4x - 41
2x = 40
x = 20
20 - 1 = 19
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.
