Answer:

7x - 2y = 39

5x + 2y = 21

Add both the equations together

12x = 60

x = 5

substitute this value for x into equation 1

35 - 2y = 39

-2y = 4

y = -2

The ordered pair (5,-2) satisfies each system.

$\dfrac{1}{9} - \dfrac{5}{6}$

Set up

$\dfrac{2}{18} - \dfrac{15}{18}$

Get all fractions to a common denominator which will allow you to subtract them

$\dfrac{2 - 15}{18}$

Subtract numerators

$\boxed{- \dfrac{13}{18}}$

Answer:

16 ride tickets.

Step-by-step explanation:

The original entry fee is $4 so you can subtract that from 12. Now you have $8. So you would double 8 since $0.50 is half of $1. 8x2 is 16.
