Open Up Resources Unit 6 Lesson 6 Two Step Equations

What is the first step in solving the following equation?
3x - 5 = 20

• multiply both sides by 5
• add 5 to both sides
• divide both sides by 5
• subtract both sides by 5

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.

-3a + 8 = 14

• a= -2
• a= -7.5
• a= 2
• a= 6

5(a + 2) = 30

• a= 5

• a= 4

• a= -4

• a= 3

-6a - 5 = -59

• a= 11

• a= -6

• a= 9

• a= 2

5x+4= -6

• 2

Lin had 90 flyers to hang up around the school. She gave 12 flyers to each of the three volunteers. Then she took the remaining flyers and divided them up equally between the three volunteers. How many additional flyers did she give to each volunteer?

• x= 18

• x= 26

• x= 10

2x + 3 = 5

• x = -2

• x = 2

• x = 1

• x = 8

Which of these is an equivalent expression to 5(x-3)

• 5x - 3

• 5x - 15

• x - 15

• 5x + 15
