Let Y be the number we want and x represent the unknown value.

 

A)

Value we want = Y

Unknown = x

condition = twelve less than a number

 

So we can write the algebraic expression as;

Y = x-12

 

 

B)

Value we want = Y

Unknown = x

condition = twice a quantity

 

So we can write the algebric expression as;

Y = 2x
