Given:
The system of equations is


To find:
The solution of the given system of equations using the substituting method.
Solution:
We have,
...(i)
...(ii)
From (ii), we get

...(iii)
Putting this value in (i), we get

Multiply both sides by 3.





Putting y=4 in (iii), we get




Therefore, the solution of given system of equations is (0,0).
