Select the algebraic equation that correctly represents the given sentence, and solve the equation. if 4 is subtracted from twice a number, the result is 12 less than the number. a. 2x – 4 = x + 12 x = 16 b. 2x + 4 = x – 12 x = –16 c. 2x + 4 = x + 12 x = 8 d. 2x – 4 = x – 12 x = –8

Divide and express 2.7/1.1 to the nearest tenth.

Step-by-step explanation:

D. 2x – 4 = x – 12            

x = –8

Step-by-step explanation:

By converting the sentence into mathematical values, we do the following:

If 4 is subtracted (- 4)

from  

twice a number (2x)

the result is (=)

12 less than (- 12)

the number (x)

So is,

-4 + 2x = -12 + x

Or, organizing the elements to put "x" variable before independent number, we have

Grouping the "x" on the left side, and the independent numbers on the right side, we change the signs (+, -) when passing them from one side to the other,  

2x – x = - 12 + 4  

Summing algebraically (in this case subtracting by having different signs) on both sides,

2x – x = x, and

-12 + 4 = -8, then

2x – x = - 12 + 4 equals

Remember the rules of algebraic sum:

(1) Numbers with identical signs are added and the sign they possess is placed.

(2) Numbers with different signs are subtracted and the sign that has the largest number is placed.
