Solving Equations/Inequalities

Solve the equation for x.
-8x - 8 + 3x - 6 = -3x + 2

• x = -8

• x = 8

• x = 2

• x = -2

Solve:
3x + 15 = 3(x + 5)

• No Solution

• x = 15

• Infinitely Many Solutions

• x = 0

Solve: 5x + 34 = -2(-7x + 1)

• x = -4

• x = 9

• x = 4

• x = 36/19

Pick the correct inequality.

• A

• B

• C

• D

Jim paid a gym membership fee of $50, plus $20 per month. Jim has paid a total of $290 to the gym. Which equation matches this situation?

• 50 + 20m = 290

• 20 + 50m = 290

• 50 + 20 = m

• 50m - 20 = 290

331 students went on a field trip. Six buses were filled and 7 students traveled in cars. How many students were in each bus? Write an equation that matches this situation.

• 331=7x+6

• 331=13x

• 331=6x+7

• 331-7=6x

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

3x - 8 < 3(x - 4) + 1

• x < -11

• no solution

• all real numbers

• x > -8

Solve for x:

• x = yb - v

• x = by - v

• x = by + v

3c + 5 = 23

• c = 3

• c = 6

• c = 7

• c = 18
