Question

Using Elimination method Solve each of the following pairs ofSimultaneous equation:
3x + 7y= 17
3x - 6y = 14​

Answer 1

Answer:

3x + 7y=17 eq. 1

3x - 6y=14 eq. 2

subtract eq. 1 and eq. 2

3x + 7y=17

3x - 6y=14

- + -

___________

13y=3

_____________

y=3/13

put the value of value of y in eq. 1

3x+7y=17

3x+7(3/13) =17

3x=17-21/13

3x=200/13

x=200/39
