Question.  17

The expression obtained when x is multiplied by 2 and then subtracted from 3 is

(A)

2x – 3

(B)

2x + 3

(C)

3 – 2x

(D)

3x – 2

Detailed Answer with Explanation:

Step 1: “x is multiplied by 2” means we take x and multiply by 2.

(2 imes x)

(= 2x)

Step 2: “then subtracted from 3” means we start with 3 and subtract the result from Step 1.

(3 - (2x))

(= 3 - 2x)

Step 3: Match with the options. The expression is (3 - 2x), which is option C.

Quick check (optional): Let (x = 1). Phrase gives (3 - 2 imes1 = 1). If we wrongly wrote (2x - 3), we’d get (2 imes1 - 3 = -1), which doesn’t match the phrase.
