One-Variable Linear Equations

After adding 4 to both sides of the equation, what do you do next:

5x - 4 = 21

5x=25

5x=25

• 20

• 5

• 10

• 0

-4x + 1 = 21

• x=120

• x=5

• x=30

• x=-5

Solve the equation:

-5x = 25

• x = 20

• x = -20

• x = -5

• x = 5

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

3x - 5 = -26

• x=-21

• x=21

• x=-7

• x=61

Solve for k:
3k + 5 = 23

• k = 4

• k = 5

• k = 6

• k = 7

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.

Solve the following equation for x:
6x + 2 = 8x - 2

• x = -1

• x = 1

• x = 2

• x = 10/14

Solve the following equation for x:
4(2x - 3) = 6x + 2

• x = 5/2

• x = 7

• x = 1

• no solution
