Question

Solve the linear equation

x+y=2
x-y=4

Answer 1

Answer:

x=6/2

y= -1

Step-by-step explanation:

Add the equations

x+y=2

+ x-y=4

-------------

2x=6

-------------

x=6/2

x=3

y=2-x

y= -1

Answer 2

Step-by-step explanation:

X+y=2---------(1)

x-y=4--------(2)

X=4+y------(3)

put (3) in (1)

(1)-------4+y+y=2

2y=-2

y= -1

put (y= -1) in (2)

(2)-------x-(-1)=4

X=4-1

X=3
