SOLVING EQUATIONS WITH VARIABLES ON BOTH SIDES REVIEW

Solve for x:
5x - 14 = 8x + 4

• x = 6
• x = -6
• x = -18/13
• x = 10/3

Solve for f:
f - 4 = 6f + 26

• f = -5
• f = 5
• f = 6
• f = -6

Solve the equation:
7x - 4 = 3 + 8x

• x = 7
• x = -7
• x = 2/7
• x = 11

Solve the equation
4x - 5x + 9 =5x - 9

• x = -3
• x = 9
• x = 3
• x = -9

What is the solution for the equation 3x - 10 = 6x + 8

• -6

• 6

• 2

• -2

Determine the solution to 3 - 7n = n - 12.

• 1.875

• 1.5

• -2.5

• -1.125

10x + 9 = 4x - 9

• 0
• 3
• -3
• -18

-5k + 10 = -2k - 14

• 8
• -8
• 2
• -2

What is the next step you should take?

1 + 4n = 10 - 14n

• Collect the variables (letters) to the left

• add 1 from both sides

• subtract 14n to both sides

What is the next step you should take?

1 + 18n = 33

• subtract 1 to both sides

• collect the numbers to the right

• add 1 to both sides

• multiply 18 to both sides
