The same of Kaleigh and Dwaynes age is 30. Three times Kaleighs age minus twice Dwaynes age equals five. How old is César if he is five years younger than Kaleigh?

Answer:

cesar is 11 1/4 years old

Step-by-step explanation:

k = kaleighs age

d = dwaynes age

3k - 2d = 5

d + k = 30

rewrite

     -k     -k

d = 30 - k

substitute

3k - 2(30 - k) = 5

3k - 60 + k = 5

4k - 60 = 5

   + 60    +60

4k = 65

/4   /4

k = 16.25

16.25 - 5 = 11.25 or 11 1/4
