Question

Devaughn is 12 years younger than Sydney. The sun of their ages is 78. What is Sydney’s age?

Answer 1

Let's denote Sydney's age as S. According to the given information, Devaughn is 12 years younger than Sydney, so Devaughn's age would be S - 12.

The sum of their ages is 78, which can be expressed as:

S + (S - 12) = 78

Now we can solve this equation for S, which represents Sydney's age.

Simplifying the equation:

2S - 12 = 78

Adding 12 to both sides:

2S = 90

Dividing both sides by 2:

S = 45

So Sydney's age is 45 years.
