-x + 2y = 3 2x – 3y = -6

s2008m [1.1K]

Answer:

x = -3

y = 0

Step-by-step explanation:

Given equations :- 

-x + 2y = 3 ....... ( i )

2x - 3y = -6 ....... ( ii )

From ( i ) 

-x + 2y = 3

-x = 3 - 2y

x = 2y - 3 ........ ( iii )

From ( ii ) 

2x - 3y = -6

2x = -6 + 3y

$x = \frac{ - 6 + 3y}{2}$

........ ( iv )

Equating ( iii ) and ( iv )

x = x

$2y - 3 = \frac{ - 6 + 3y}{2}$

4y - 6 = -6 + 3y

4y - 3y = -6 + 6

y = 0

Putting value of y in ( iii )

x = 2y - 3

x = 2 ( 0 ) - 3

x = -3

At the city museum, child admission is 5.50 and adult admission is 8.8 . On Thursday, three times as many adult tickets as child

tigry1 [53]

Answer:

Step-by-step explanation:

Adult tickets = x

Child tickets = 3(Adult tickets) = 3x

The cost of child admission is $5.50, and the cost of adult admission is $8.80. Multiply the cost of admission by the variables and set equal to the total sales.

8.8(x) + 5.5(3x) = 663.6

8.8x + 16.5x = 663.6

25.3x = 663.6

x = 26

Child tickets = 3x

Child tickets = 3(26)

Child tickets = 78

78 child tickets were sold that day.
