Answer:
jackson is 12
Step-by-step 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
Answer:
12
Step-by-step 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
