Question

What is the solution to this system of linear equations? x + y = 4 x − y = 6

Answer 1

Answer:

x = 4-y

substitute the value of x in 2nd equation

4-y-y=6

4-2y=6-

-2y = 2

y= -1

then substitute the value of y u will get x

in 1st e

x-1=4

x=5

Step-by-step explanation:

Answer 2

$x + y = 4$
$x - y = 6$
$2x = 10$
$x = 5$
$5 - y = 6$
$y = - 1$
