Writing Algebraic Expressions

Translate this phrase into an algebraic equation:

A number tripled subtracted from 60 is the same as 21.

• 3c − 60 = 21

• 60 − 3 = 21c

• 60 − 3c = 21

• c(60 − 3) = 21

Translate: Six fewer than twice a number is four.

• 6 - 2x = 4

• 2x - 6 = 4

• x² - 6 = 4

• 6 - x² = 4

Translate this phrase into an algebraic equation:

One third of a number increased by 7 is 13

• 1/3 ÷ n + 7 = 13

• 1/3(n+7) = 13

• 1/3n + 7 = 13

Translate this phrase into an algebraic equation:

Twice the difference of a number and 16 is equivalent to 28.

• 2x + 16 = 28

• 2x - 16 = 28

• 2(x + 16) = 28

• 2(x - 16) = 28

Translate this phrase into an algebraic equation:

Three times the sum of a number and 7 is equivalent to 57.

• 3x + 7 = 57

• 3(x + 7) = 57

• 7x + 3 = 57

• 7(x + 3) = 57
