x + 5y = 7 ;

6x - 10y = 18 ;

x = -5y + 7 ;

6(-5y + 7) - 10y = 18 ;

-30y + 42 - 10y = 18 ;

-40y + 42 = 18 ;

-40y = 18 - 42 ;

-40y = -24 ;

y = -24/-40 ;

y = 3/5 ;

x + 5(3/5) = 7 ;

x + 15/5 = 7 ;

x + 3 = 7 ;

x = 7 - 3 ;

x = 4 ;

Solution set: (4, 3/5)

6x - 10y = 18 ;

x = -5y + 7 ;

6(-5y + 7) - 10y = 18 ;

-30y + 42 - 10y = 18 ;

-40y + 42 = 18 ;

-40y = 18 - 42 ;

-40y = -24 ;

y = -24/-40 ;

y = 3/5 ;

x + 5(3/5) = 7 ;

x + 15/5 = 7 ;

x + 3 = 7 ;

x = 7 - 3 ;

x = 4 ;

Solution set: (4, 3/5)

There are 8 pints in a gallon. In 3 gallons are there 24 pints.

8 pints/gallon x 3 gallons = 24 pints.

8 pints/gallon x 3 gallons = 24 pints.
