Question

Y=x+3 and y=x-y help me ​

Answer 1

Explanation:

Given

y = x + 3.....equation 1

y = x - y

or y + y = x

or 2y = x

or y = x / 2......equation 2

Now

Putting equation 2 in equation 1

x / 2 = x + 3

x - x/2 = - 3

2x - x = - 3

2

x / 2 = -3

x = - 6

Now

y = x/ 2

= - 6/2

= - 3

Hope this helps
