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

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

Solve for x:
8x - 10 = -34

• 4
• 3
• -3
• -24

What is the first step in solving this equation:
5x + 7 = 12

• Divide by 5
• Subtract 5
• Multiply by 7
• Subtract 7

x + 4 = 11

• a = 36

• a = 6

• a = -6

• a = -36

3(3x - 6) = 18

• x = 4
• x = -4
• x=8
• x= -12

Solve:
6(5x - 3) + 2 = 14

• 2
• .5
• -1
• 1

6x - 4 ≥ 26

• x ≥ 3.67
• x ≥ 5
• x < 5
• x ≤ 5

Do you flip the sign?
-3x + 2  ≤  22

• YES
• NO
