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

Solve the Equation:
12.5 -4g = -2g - 3.5

• g = -8

• g = 10

• g = 8

• g = 1.25

Solve the Equation:
^{1/4 - 1/2r = -3/4r}

• r = 1

• r = -1

• r = 0

• r = 10

Solve the Equation:
-2h - 16 = 3h - 6

• h = 10

• h = 2

• h = -2

• h = -10
