Answer 1

if it helps try to make an equation out of it

Answer 2

let current age of luis=\(l_u\)
and
let current age of kevin=\(k\)

so luid is 30 yrs younger than kevin hence,

\(\large\tt \begin{align} \color{black}{l_u=k-30------\color{red}{(1)}
}\end{align}\)

luis's age two yrs ago would be \((l_u-2)\)
and kevin's age two yrs ago would be \((k-2)\)

two yrs ago ,kevin was 4 times as old as luis
\(\large\tt \begin{align} \color{black}{(k-2)=4(l_u-2)-------\color{red}{(2)}}\end{align}\)

solve 1 and 2 for \(k\)
