Translate the statement into an equation:
6 less than twice a number is 4

• 2n - 6 = 4

• 6 - 2n = 4

Twice a number is 24.

• 2n = 24

• 2/n = 24

• 2 + n = 24

• 2 - n = 24

Translate the statement into an equation:
5 less than 3 times a number is 7

• 3n - 5 = 7

• 5 - 3n = 7

5 less than a number is 15.

• x - 5 = 15

• 5 - x = 15

• 15 - x = 5

What equation is being represented by the model.
yellow (positive)

• 2x - 4 = -10

• 2x + 4 = 10

• x + 4 = 10

• x - 4 = -10
