Ajay is younger than Vijay by $5$ years. Sum of their ages is $25$ years. What is Ajay's age?

Solve $2x+y=5$ and $3x-y=5$

Solve $x-2y=-1$ and $2x-y=7$

Solve $x+y=11$ and $2x-3y=7$

Solve $2x+y=-2$ and $3x-y=7$

Solve $2x-y=5$ and $3x+2y=11$

Solve $x-2y=-2$ and $x+2y=10$

By equating coefficients of variables, solve $3x-4y=7$ and $5x+2y=3$

By equating coefficients of variables, solve $5x+7y=17$ and $3x-2y=4$
