y= 7 (a)

y= 2x-5 (b)

Replace (a) on (b) ans solve for x:

7 = 2x-5

Add 5 to both sides of the equation:

7+5 = 2x -5 +5

12 = 2x

Divide both sides by 2

12/2 = 2x/2

6 = x

Solution:

x=6, y=7

Maslowich

Answer:

Approximately 23,433 children will have cancer.

Step-by-step explanation:

3/1500 can be simplified to 1/500, which can also be written as 0.002. To find the number of children who have cancer, we do 11,721,722 * 0.002, which gives us 23,433.444 which we can round to 23,433.
