Question

I think of a number $x$ , add $3$ to it. The result is then multiplied by $2$ . The final result is $42$. The correct algebraic statement is

• A. $x+3\times 2=42$
• B. $(x+3)\times 2=42$
• C. $x+3=2\times 42$
• D. $x\times 2+3=42$

Answer 1

The correct option is B

$(x+3)\times 2=42$

The number is $x$

When $3$ is added , the result is $x+3$

Then the result is multiplied by $2$ , so it results to $(x+3)\times 2$

This finally results to $42$, hence we can say $(x+3)\times 2=42$

Hence, option b is the correct option
