Question

What is the solution for:
y=x+3
y=2x

Answer 1

It is given to you in the second equation that \(\sf{y = 2x}\) .

So, just put y = 2x in the first equation : y = x + 3

As y = 2x(from eq. 2)

So, eq.1 becomes :

2x = x + 3

Answer 2

Now, solve for "x" and then for "y" . Can you do that?

Answer 3

2x=x+3
2x-x=3
x=3
Answer: 3
