Question

The solution of the linear equation x-y=2 and x+y=4 is ?

Answer 1

Answer:

given x-y =2--------1

X+y=4-------2

Step-by-step explanation:

add 1and 2

x-y+y+x=6

2x=6

x=3

and y=1

Answer 2

Answer:

subtracting eq1 (x-y=2) from eq2 (x+y=4)

x+y=4

x-y=-2

_____

0+2y=2

y=2÷2

y=1

so,

y=1;

x-1=2

x=1
