First Step Equation

x = 20

• x = 20

• x = 7

• x = 10

• x = 3

Solve for x : 5x = 95

• x = 19

• x = 90

• x = 100

• x = 95

What would be the best first step to solving the equation?

• multiply both sides by 3

• multiply both sides by 4

• divide both sides by 3

• divide both sides by 4

Solve for x : 3 + x = 21

• x = 18

• x = 24

• x = 7

• x = 63

Solve for x : x + 5 = 25

• x = 30

• x = 5

• x = 20

• x = 25

If 5x = 25 , what is the first step to solve for x?

• Divide by 5 on both sides

• Add 25 to both sides

• Subtract 5 from both sides

• Multiply by 5 on both sides

Solve for x : x - 17 = 34

• x = 2

• x = 50

• x = 17

• x = -17

Solve for x : x - 3 = 12

• x = -4

• x = 9

• x = 15

• x = 36

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides

• add 5 to both sides

• subtract 15 from both sides

• subtract 5 from both sides

What equation matches this situation?
Robyn had some video games then bought 4 more.  Now she has a total of 10 games.

• v - 4 = 10

• v + 4 = 10

• 10 - 4 = v
