Question

What is the value of x in the equation $2x+4=18$?

• A. $5$
• B. $6$
• C. $7$
• D. $\frac{7}{2}$

Answer 1

The correct option is C $7$

Given, $2x+4=18$
Now, subtracting 4 on both sides of the equation, we get:
$2x+4-4=18-4$
$2x=14$
Dividing both sides of the equation by 2, we get
$\frac{2x}{2}=\frac{14}{2}$
$x=7$
