Answer 1

a joke and a cartoon together cost $80

c=$15 j=$65

Explanation:

j=joke

c=cartoon

8j +6c = 610

6j+8c = 510

Multiply the first by 8

Multiply the second by -6

64j +48c = 4880

-36j -48c = -3060

ADD both (c will cancel)

28j = 1820

j= 65

PLUG j

8(65) + 6c = 610

520+6c = 610

6c= 90

c = 15

j + c = 65+15 = 80
