Equations

The objective when solving an equation is to....

• isolate the variable.
• check the solution.
• guess and check.
• Combine Like Terms.

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.

6z + 3 -4z = 9

• z = 3
• z = 60
• z = 30
• z = 1

11b+7=40

• 2
• 1
• 4
• 3

Solve for x:
52 = -5x - 3

• x = 11
• x = -11
• x = 275
• x = -275

Solve for k:
3k + 5 = 23

• k = 4
• k = 5
• k = 6
• k = 7

-4x+1=21

• x=120
• x=5
• x=30
• x=-5

4 = 2(x + 3)

• 1/2
• 7/2
• -1
• 5

5=7s-9

• 2
• 6
• 7
• 8

Solve for x:
-30 - 5x = 120

• x = 18
• x = -18
• x = 30
• x = -30
