Question

Elimination Method
X + y = 5
3x + y=11​

Answer 1

Answer:

x+y=5

3x+y=11

(-) ( -) =(-)

-2x=-6

x=-6/-2

x=3

putting x=3 in eq.

x+y=5

3+y=5

y=5-3

y=2

Answer 2

Answer:

x + y = 5........(1)

3x + y = 11......(2)

By Subtracting equation 1 and 2

x + y = 5

3x + y = 11

(-) (-) (-)

2x = 6

x = 6/2

x=3

By Substituting x=3 in equation (1)

x + y=5

3+y=5

y =5-3

y = 2

therefore, x=3 and y=2
