Taxi charges in a city consist of fixed charges per day and the remaining depending upon the distance travelled in kilometres. If a person travels $110 \mathrm{km}$, he pays $₹690,$ and for travelling he pays $₹1050$. If the fixed charges per day is $₹x$ and the rate per km is $₹y$, then find the value of $x+y$ ?

One equation of a pair of dependent linear equations is $-5x+7y=2$

The second equation can be:

Solve simultaneous linear equations in two variables by the method of elimination.

$41x+53y=135, 53x+41y=147$

Solve simultaneous linear equations in two variables by the method of elimination.

$\frac{x}{2}+\frac{y}{3}=2, \frac{x}{4}+\frac{y}{2}=2$
