Solves Problems Involving Algebraic Expressions

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

• n - 5 = 6

• 5 - n = 6

Translate this sentence into an equation.

72 is the product of 8 and Steve's age.

Use the variable h to represent Steve's age.

• 72 = 8 + h

• 72 = 8h

• 72 = 8 - h

• 72 = 8/h

Five less than twice a number is equivalent to 47. 

• 5 - 2x = 47 

• 2x - 5 = 47 

• 5x - 2 = 47 

• 2 - 5x = 47 

3 W = 12

• w= 3

• w = 5

• w = 4
