To Find :-We have to find the value of x and y.Concept used :-Linear equations are those equations which having highest power of degree as 1 .Linear equations can be solved by subsitute method, elimination method and cross multiplication method. Here, I have used substitution method to make calculation easier. In subsitute method, you have to subsitute the value of one variable of eq(1) in eq(2) .Let's Begin :-

Here,

We have two equations, let consider these two equations as eq(1) and eq(2) that is,

By solving eq(1) :-

Subsitute eq(3) in eq(2) :-

Thus, The value of y is 5

Now,

Subsitute the value of y in eq(1) :-

Hence, The value of x and y are 5 and 3 .

Equation 1 :-

Equation 2 :-
