N = 9 * 27 + 2 * 31 - 28
n = 243 + 62 - 28
n = 305 - 28
n = 277
Firstly do the multiplications and divisions, then additions and substractions.

Answer:
j=2
Step-by-step explanation:
<em>First, subtract by 5 from both sides of equation.</em>
<em>5-j-5=3-5</em>
<em>Simplify.</em>
<em>3-5=-2</em>
<em>-j=-2</em>
<em>Divide by -1 from both sides of equation.</em>
<em>-j/-1=-2/-1</em>
<em>Simplify, to find the answer.</em>
<em>-2/-1=2</em>
<em>It change negative to positive.</em>
<em>j=2 is the correct answer.</em>
<em>I hope this helps you, and have a wonderful day!</em>
