Here's an equation. Jessica wants to add 5 to both sides to cancel out the 5 and get her answer. Would she be correct in doing this?
x + 5 = 23
NO! Jessica should SUBTRACT 5 on both sides to cancel out the 5 on the left side and then to get 18 on the right side.

If a problem uses the variable "y" in their story, it's ok for me to use a different variable like "x" or "a" in my answer.
While it may not change the actual value of your answer, typically you want to use the same variable that the story provides.

Mr. Wiik and his family go on a road trip. In the first day, they drive 220 miles. Every day they drive 180 miles after that. Their trip will cover a total of 1300 miles. Is this equation a correct model of the trip?
180d + 220 = 1,300
Yes! Even though the 180d comes first in the equation, you can switch the order and the equation will still have the same meaning.
180d + 220 =1300 is the same thing as
220 + 180d = 1300

Expand to write an equivalent expression. hint** use the distributive property.
-35m + 10

Was this expression combined correctly?
7.8m - 5n + 3g - 11n + 16.8m - 99
= -9m - 6n + 3g + 99
No, it was not combined correctly. Here is the correct answer.
7.8m - 5n + 3g - 11n + 16.8m - 99 =
24.6m - 16n + 3g - 99

It's a hot summer day and you're filling up a kiddie pool to sit in. The kiddie pool holds 24 gallons of water and it fills up at a rate of 0.8 gallons a minute. If there are already 6 gallons in the pool, how long will it take to fill up the remaining amount? Write an equation to represent this situation.
0.8m + 6 =24

A student used the distributive property to expand the expression. Did they do it right?
4(x - 10) became 4x + 40
No! The second term in the parentheses is a -10 so 4(x - 10) should have become 4x - 40 instead of 4x + 40.

Simplify the expression. hint** use distributive property.
1/2(2y + 88)
1/2(2y + 88) becomes y + 44 after using the distributive property.
