Translate: 
Four times a number plus six is 30.

• 4 + 6 = 30
• 4x + 6 = 30
• x + 4 times 6 = 30
• 30 = 4x

Translate the sentence into an equation:
Four more than six times a number is 18.

• 10x = 18
• 4x + 6 = 18

Write an equation. 
Three times a number plus five times the same number is 40. 

• 3x + 5 = 40
• 3x - 5 = 40
• 3x + 5x = 40
• 3x - 5x = 40

Write an equation.
A number is doubled, then 9 is added. The result is 23.

• 2x + 9 = 23
• 2x - 9 = 23
• 2x + 9x = 23
  2x + 9x =23
• 9 - 2x = 23

Simplify 
-2y + 8 + 7y + 5

• -5y-13
• 9y+13
• 5y+13
• 9y-13
