Question

Jeannie is 8 years older than her younger sister April. When added together, their ages equal 198. How old is April?

Answer 1

let \(j\) be Jeannie's age, and \(a\) be April's age.

\[j = 8+a\]because Jeannie is 8 years older than April

\[a+j = 198\]because their ages add to 198

substitute the previous equation:
\[a+(8+a) = 198\]
Solve for \(a\) to find April's age

Answer 2

April is 95
