Let's solve the equation step-by-step:
Given equation:
[tex]\[ 2x + 6 = 20 \][/tex]
1. Subtract 6 from both sides of the equation:
[tex]\[ 2x + 6 - 6 = 20 - 6 \][/tex]
Simplifying, we get:
[tex]\[ 2x = 14 \][/tex]
2. Divide both sides by 2 to solve for [tex]\( x \)[/tex]:
[tex]\[ \frac{2x}{2} = \frac{14}{2} \][/tex]
Simplifying, we get:
[tex]\[ x = 7 \][/tex]
Therefore, the value of [tex]\( x \)[/tex] is 7.
So, the correct answer is:
[tex]\[ \boxed{7} \][/tex]
Thus, the answer is B. [tex]\( x = 7 \)[/tex].
