Answer:

x = \frac{1}{5} , y = 6

Step-by-step explanation:

5x + y = 7 → (1)

20x + 2 = y → (2)

Substitute y = 20x + 2 into (1)

5x + 20x + 2 = 7

25x + 2 = 7 ( subtract 2 from both sides )

25x = 5 ( divide both sides by 25 )

x = \frac{5}{25} = \frac{1}{5}

Substitute this value into (2) and evaluate

20(\frac{1}{5} ) + 2 = y

4 + 2 = y , so

y = 6

I used 2/3 for tickits and 1/6 on popcorn how much money is left
posledela

Answer:

You would have 1/6 of your money remaining.

Step-by-step explanation:

Let's write an equation for this.

1 - (2/3 + 1/6)

First, let's multiply the numerator and denominator of 2/3. You get 4/6!

1 - (2/3 + 1/6)

1 - (4/6 + 1/6)

Next, let's add 4/6 and 1/6. You get 5/6!

1 - (4/6 + 1/6)

1 - 5/6

Finally, let's turn 1 into 6/6 and do 6/6 - 5/6!

1 - 5/6

6/6 - 5/6

1/6

You would have 1/6 of your money remaining.
