520 + 6x = 1000
Answer:
-x+20=31
Step 1: Subtract 20 from both sides.
−x+20−20=31−20
−x=11
Step 2: Divide both sides by -1.
−x
−1

Answer:
Total crackers on the plate are 12
Step-by-step explanation:
Manuel ate crackers = 
His brother ate crackers = 
Crackers left on the plate = 5
We need to find how many crackers were there on the plate.

So, we get x = 12
Therefore, total crackers on the plate are 12
