Problem: Gauss Elimination Back Substitution 7y+2x=11,3x-y=5 [ Calculator, Method and examples ]

Your problem `->` Gauss Elimination Back Substitution 7y+2x=11,3x-y=5

Total Equations are `2`

`2x+7y=11 -> (1)`

`3x-y=5 -> (2)`

Converting given equations into matrix form

`R_2 larr R_2-3/2xx R_1`



`2x+7y=11 ->(1)`

`-23/2y=-23/2 ->(2)`

Now use back substitution method
