• -4

Solve:
7x + 19 = -2x + 55

• 4
• 14.8
• 8.2
• -4

What is the first step in solving for w in the equation 3w + 5 = 14?

• Add 5 to both sides of the equal sign

• Divide by 3 on both sides of the equal sign

• Subtract 5 from both sides of the equal sign

• Multiply by 3 on both sides of the equal sign

4x + 1 = 7x - 5

• -1
• 2
• 6/11
• 8

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k

Which of the following is the result after applying the Distributive Property?

• 6 = 3x - 6

• 6 = -3x - 6

• 6 = -3x + 6

• 6 = 3x + 6
