Cross multiply to get answer<br> x + 5/10 = 2x-3/15
Andreyy89

Once cross multiplied you end up with this:

15x+75=20x−30

Next subtract 20x from both sides.

15x+75−20x=20x−30−20x

−5x+75=−30 -----------> Answer

Now subtract 75 from both sides

−5x+75−75=−30−75

−5x=−105

Now divide by -5 on both sides.

-5/-5x = -105/-5

ipn [44]

Answer:

The number of adults is 1,200

Step-by-step explanation:

Let

x------> the number of children

y------> the number of adults

we know that

x+y=1800 -------> equation A

2x+4y=6000 -------> equation B

Multiply equation A by -2

-2(x+y)=-2*1800 --------> -2x-2y=-3600 ------> equation C

Adds equation B and equation C

2x+4y=6000\\-2x-2y=-3600\\---------\\4y-2y=6000-3600\\2y=2400\\y=2400/2\\y=1200
