Step 1
Step 2
Step 3
Step 4
Find the error
There is no error
They should have subtracted 3 to both sides
They should have subtracted 2x to both sides
They should have divided 7 to both sides
The answer should be 6/7
A student solved this problem. Which, if any, describe the mistake(s) made?
He distributed incorrectly on step 1. 6(x + 2) = 6x + 8
He added 3x twice to the left side and added nothing to the right side. He made the scale unbalanced.
On step 4, he should have added 12 to get rid of an added 12.
There are no mistakes
What error did the student make when solving the equation:
5x + 6 = 66
5x - 6 = 66 -6
5x = 60
5*5x= 60*5
x = 300
Simplify the expression -2(x + 5).
-2x + 10
-2x - 10
-2x + 5
-2x - 5
Use the Distributive Property
5(2x + 3)
10x + 3
10x + 15
25x
7x + 8
Use the Distributive Property to rewrite the expression.
-3(2x + 2y - 5)
-6x - 6y - 15
-6x + 6y + 15
-6x - 6y + 15
-6x - 2y + 5
