Question

Jackson is two times older than Shelly if the sum of their ages is 18 how old is Jackson

Answer 1

12

Explanation:

since we know that Jackson is 2x Shelly - we can use trial and error.

for instance,

let's suppose Shelly is 6; that means that Jackson must be 12 (6 x 2)

we can check this answer by adding the two;

12 + 6 = 18

therefore, Jackson is 12

Answer 2

jackson is 12

Explanation:

let the age be represented by x

jackson is 2 times older than shelly so

2x is jackson’s age and x is shelly’s age

since the sum of their ages is 18 then:

2x + x = 18

solve:

3x = 18 ➔ divide by 3 on both sides

x = 6

so now we know shelly is 6

jackson is 2 times older than her so:

2(6) = 12

hope this hello and hope it is right
