Find the Error
What error did the student make when solving the equation:
1/5x + 6 = 3/5x + 5
1x + 6 = 3x + 5
-2x + 6 = 5
-2x = -1
x = 1/2

• The student found an incorrect common denominator

• The student did not multiply all terms by the common denominator

• The student did not use opposite operations appropriately

• The student did not correctly eliminate the variable from one side of the equation

13y - 18 = -5y + 36

• y = 3

• y = -3

• y= 9

• y = -9

3x - 32 = -7x + 28

• x = 6

• x = -6

• x = 1/6

• x = -1/6

4k + 24 = 6k -10

• k = 17

• k =-17

• k= 5

• k = 1/5

13x = 32 + 5x

• x = 4

• x = -4

• x = 1/4

• x = -1/4
