Question

What remains after 4 is subtracted on both sides is $2x=6$ Which of the following operations can I perform next to obtain the value of $x$?

• A. Divide both sides of the equation by 2
• B. Shift all quantities to one side of the equation.
• C. Multiply 2 on both sides of the equation
• D. Both A and B

Answer 1

The correct option is A

Divide both sides of the equation by 2

Now, since $2x=6$, we divide both sides of the equation by 2 to get $\frac{2x}{2}=\frac{6}{2}$ or $x=3$
Also, we can shift the coefficient of x, i.e., 2 to the right hand side, by division. Hence, $x=\frac{6}{2}=3$
