Answer:

x = 2, y = -1.

Step-by-step explanation:

2x + y = 3

x  -   y  = 3

Adding the 2 equations eliminates y:

3x = 6

x = 2.

Substitute for x in the first equation:

2(2) + y = 3

y = 3 - 4

y = -1.

Check the results by substitution in equation 2:

2 - (-1)

= 2 + 1 = 3 .

Checks OK.

At a lunch buffet, the price for an adult plate is $19, and the price for a child plate is $8. On Tuesday, a total of 32 plates
mestny [16]

Answer:

Adult plate = 21 , child plate = 11

Step-by-step explanation:

number of adult plate = a , no of child plate = c

$487 = $19a + $8c (equation 1)

32 = a + c (equation 2)

Multiply equation 2 by 8 gets you:

256 = 8a + 8c (equation 3)

Solve equation 1 and equation 3 simultaneously:

487 = 19a + 8c (equation 1) minus

256 = 8a + 8c (equation 3) :

231 = 11a

a = 231/11

a= 21

Substitute a = 21 into equation 2 :

32 = 21 + c

c = 32 - 21

c = 11

So 21 adult plates and 11 child plates were sold.
