Two-Step Equations

3c + 5 = 23

• c = 3

• c = 6

• c = 7

• c = 18

4x + 7 = 23

• x = 16

• x = 4

• x = 9

• x = 12

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

Figure out what n equals in this equation:
6n + 4 = -26

• n=-6

• n= -5

• n= 8

• n= -4

6.    -3x + 5 = -13

• x = -5

• x = 2

• x = -6

• x = 6

Solve for x:
-30 - 5x = 120

• x = 18

• x = -18

• x = 30

• x = -30

x/5 - 13 = 20

• 145

• 165

• 180

• 190

10.    x / 2  - 5 = 3

• x = -2

• x = 2

• x = 16

• x = 8

12 = 4 - 4x

• 10

• 8

• 4

• 2

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
