Solving Single Variable Equations

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

• isolate the variable.

• check the solution.

• guess and check.

• Combine Like Terms.

Solve for x.

15 = x + 6

• x = 9
• x = 15
• x = 6
• x = 12

Solve for x.

6x = 48

• x = 6

• x = 7

• x = 8

• x = 48

Solve for w.

-6w + 1 = -11

• 2
• 1.2
• 12
• -2

-3a + 8 = 14

• a= -2
• a= -7.5
• a= 2
• a= 6

-5 - 6a = -59

• a= 11
• a= -6
• a= 9
• a= 2

33 = 4a - 7

• a=-10
• a=10
• a=4.5

-3a + 8 = 14

• a= -2
• a= -7.5
• a= 2
• a= 6
