Answer 2

Answer:

x = -5

y = 8

therefore x+y = 3

Step-by-step explanation:

Whenever the coefficients are x and y variables are exchanged,

First add the two equations and then subtract the two equations.

Equations:

6x + 5y = 9

5x + 6y = 24

Step 1 :-

Add the two equations.

6x + 5y + 5x + 6y = 9+ 24

11x + 11y = 33

Dividing throughout by 11

x + y = 3 (1)

Step 2 :-

Subtract the two equations

6x + 5y - 5x - 6y = 9 - 24

x - y = -13

x = y-13 (2)

Substitute (2) in (1)

y - 13 + y = 3

2y = 16

y = 8

Substitute y=8 in (1)

x + 8 = 3

x = -5
