Hi student, let me help you out!

Let's substitute the value of x for x: [tex]\mathrm{2(3)+y=7}[/tex].
Upon simplifying, we get: [tex]\mathrm{6+y=7}[/tex].
Now we solve for y by subtracting 6 from both sides: [tex]\mathrm{1=y}[/tex]
Thus, the solution is [tex]\bigstar~\underline{\boxed{\mathrm{y=1}}}[/tex]
Hope it helped you out, ask in comments if any queries arise.
