x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 
• Subtract 62 from each side.
• Multiply each side by 62.
• Add 123 to each side.

7(2x - 4) = 42

• x= 5
• x= 8
• x= 2
• x= 9

-3a + 8 = 14

• a= -2
• a= -7.5
• a= 2
• a= 6

33 = 4a - 7

• a=-10
• a=10
• a=4.5

0 = 8z + 8 

• -1
• 1
• 0
• 8

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

2x - 3 + 4x = 27

• 12
• 4
• 5
• 15

-11 + 3(b + 5) = 7

• 1
• -1
• 3
• -3

Solve:
3x + 15 = 3(x + 5)

• No Solution
• x = 15
• Infinitely Many Solutions

3r - 5 = 2r

• No solution
• Infinitely many solutions
• r = 5
