What is the Least Common Multiple for the values in the equation:
2/5x + 3/4 = 3/5x + 8

• 20
• 9
• 10
• 40

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

• r = 1
• r = -1
• r = 0
• r = 10

Simplify each equation. Tell whether the equation has one, no, or infinite solutions.
3x - 8 = 3(x - 4) + 1

• one
• no solutions
• infinite solutions
