a) y = x-2 and x + y = 4​

Answer 1

Step-by-step explanation:

Adding the two equations: -

(X-Y)+(x-y)=2+4

2x=6

X=6/2

X=3

Now putting the value of ‘x’ in 1st equation, we get

3-y=2

Y=3–2

Y=1

Answer 2

Hope it will help you

Step-by-step explanation:

Given y= x-2 and x + y = 4

Then,x+x-2=4

2x-2=4

2x=4+2

2x=6

x=6/2

x=3

This is your answer
