answer:

a+c =11

a +3c = 19

a =7   and c = 4

step-by-step explanation:

let a = price of one adult

c = price of one child

we know one adult and one child = 11

a+c =11

mrs smith and 3 children spent 19

a +3c = 19

we have 2 equations and 2 unknowns

a+c =11

a +3c = 19

multiply the first equation by -1 so we can eliminate a

-a-c=-11

a+3c=19

2c = 8

divide by 2

2c/2 = 8/2

c=4

each child equals 4 dollars

now we need to find a

a + c= 11

a+4 = 11

subtract 4 from each side

a+4-4 = 11-4

a = 7

the adult is 7
