Answer 1

Answer:

Sally is currently 4 years old.

Step-by-step explanation:

Kaden is 18 years older than Sally now. In 5 years, Kaden will be 3 times as old as Sally. How old is Sally now?

Let Kaden's current age be $k$ and Sally's current age be $s$. We can write the following algebraic equation using the fact that Kaden is currently 18 years older than Sally:

$k=s+18$

Next, we will use the fact that in 5 years, Kaden will be 3 times as old as Sally. If Kaden and Sally's current ages are $k$ and $s$ respectively, then their ages in 5 years will be $k+5$ and $s+5$ respectively. Therefore, we have:

$k+5=3(s+5)$

We have two equations with two variables. To solve for either variable, we need to create an equation with only one variable. Therefore, let's substitute the first equation into the second:

$(s+18)+5=3(s+5)$

Distribute and combine like terms:

$s+18+5=3s+15,\\s+23=3s+15$

Subtract $s$ from both sides, then subtract 15 from both sides:

$8=2s$

Divide both sides by 2:

$s=\frac{8}{2}=\boxed{4}$

Therefore, Sally is currently 4 years old.

Answer 2

Answer:

Sally is 4 years old now.

Step-by-step explanation:

Let Sally's age = x

Kaden's age = x + 18

In 5 years, they are both 5 years older than now.

Sally will be x + 5

Kaden will be x + 18 + 5 = x + 23

"In 5 years, Kaden will be 3 times as old as Sally."

x + 23 = 3(x + 5)

x + 23 = 3x + 15

-2x = -8

x = 4

Answer: Sally is 4 years old now.
