Equations and inequalities review

What is the first step in solving this equation:

5x + 7 = 12

• Divide by 5

• Subtract 5

• Multiply by 7

• Subtract 7

Solve for x:
8x - 10 = -34

• 4
• 3
• -3
• -24

Solve:
6(5x - 3) + 2 = 14

• 2
• .5
• -1
• 1

-4x-7≥21

• x≥7
• x≥-7
• x≤8
• x≤-7

*

• 6
• 5
• -5
• 6

Which is a solution of
5(v + 3) - 10v > -10

• v < 5
• v > 5
• v > -5
• v < -5

Solve the inequality:
-2x + 5 < x - 7. Which value is in the solution set?

• 2
• 4
• -1
• 5

solve 26 + m ≥ 5(-6  + 3m)

• m ≥ 4
• m = 4
• m ≥ -4 
• m ≤ 4

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
