Solve Equations Using Whole Numbers

What is the first step in solving this equation:
6x - 5 = 12

• Divide by 5
• add 5 to both side

• Multiply by 7
• Subtract 7

Solve for x:
8x - 10 = -34

• 4
• 3
• -3
• -24

Solve:
3(x - 2) = 18

• 6.7
• 4
• 8
• -4

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

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5

Solve.   n - (-2) = -14

• -16
• 16
• 12
• -12

7x = 3x + 24

• 6
• 10
• 14
• 4

2x = x + 3

• 6
• 3
• 2
• x

5 - 2t = 3t

• 1
• 5
• 3
• 2

17 = x + 3

• x = 20
• x = 14
• x = 13
• x = 19
