3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

Multiply the 2nd row by 3.

Step-by-step explanation:

Multiply the second row by 3.  Then we have:

2x + 3y = 18

21x - 3y  = 30

Now, if we combine these two equations, y will disappear and we'll have:

23x = 48, so that

x = 48/23.

Divide the total amount by the portion size.

= 3 1/2 ÷ 1/4
convert 3 1/2 to improper fraction

= (2*3+1)/2 ÷ 1/4
= 7/2 ÷ 1/4

to divide a fraction, we multiply by the reciprocal/inverse of 1/4

= 7/2 * 4/1
multiply numerators, then multiply denominators

= (7*4)/(2*1)
= 28/2

= 14

ANSWER: 14

Hope this helps! :)
