Translating Equations and Solving Equations

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

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
