Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

Solve: 
3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

To Solve the Equation Below, you'd
x - 62 = 123

• add 62 to each side
• subtract 62 from each side
• multiply each side by 62
• Add 123 to each side

Translate into an inequality:
2 times a number is greater than 6

• 2-x<6
• 2x>6
• 2x>-6
• 2x<6

21 = 9x+3 

• x= 45
• x=3
• x=2
• x=21
