Which equation is written in STANDARD form?

• y = 1/2x + 2
• y - 3 = -5(x + 2)
• -7x + 2y = 9
• 3x + 2 = y

Find the Error
What error did the student make when solving the equation:
⅕x + 6 = ⅗x + 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
