Linear equations (one variable)

Solve the equation:

4x - 5x + 9 = 5x - 9

• x = -3

• x = 9

• x = 3

• x = -9

Solve for a: 2(a + 3) - 5 = 3a - 1

• -2

• 5

• 0

• 2

Order the following Steps to Solve: 3 - 6x = 2x + 27

• Sub 27 from both sides

• Add 6x to both sides

• Divide both sides by -8

• Simplify

  x = -3

Answer explanation

3 - 6x = 2x + 27

+6x +6x Add 6x

=============

3 = 8x + 27

-27 - 27 Sub 27

=============

-24 = 21

3x /3 = 21/3 Div by 3

x = 7 Simplify

Solve 3x+7=2x+10

• x = 3

• x = 2

• x = 5

Solve the following equation:

4x + 1 = 8x − 3

• x = 1

• x = 2

• infinitely many solutions

• no solutions

62-7x=-10+5x

• I don't want to even try to solve this. 

• 20

• 45

• -15

14 x - 20 = 22 + 21 x

• x = - 6

• x = 1

• x = -2

• x = - 7

what is x + 9 = 18 - 2x

• x = 3

• x = -3

• x = 4

• x = -4

8v + 1 = 7v -20

• 20

• 1

• -21

• -12
