==========================================

Step-by-step explanation:

The steps you have so far are correct. You just need to multiply both sides by -3

Doing so will clear out the fractions and you'll be left with 19 = x, which is the same as x = 19

Let's check that answer:

$y = -(1)/(3)x + 7\\\\y = -(1)/(3)*19 + 7\\\\y = (-19)/(3) + 7*(3)/(3)\\\\y = (-19)/(3) + (21)/(3)\\\\y = (-19+21)/(3)\\\\y = (2)/(3)\\\\$

So the answer is confirmed.
