1) x + y = 4

2) x - y  = 6
-----------------

Add like terms of the two equations


2x + 0 = 10
       2x = 10
           x = 5

Look at the first equation:

x + y = 4
5 + y = 4
y = 4 - 5 = -1
y = -1

Answer:  ( 5, -1)

The solution to this system of linear equation should be (-5,1).

  • The calculation is as follows:

x + y = 4


x - y  = 6

Now

2x + 0 = 10

2x = 10

x = 5


Now

x + y =4

5 + y = 4

y = -1
