To solve the equation [tex]\( 4x = 124 \)[/tex], we need to isolate the variable [tex]\( x \)[/tex]. Here is the step-by-step solution:
1. Start with the given equation:
[tex]\[
4x = 124
\][/tex]
2. To isolate [tex]\( x \)[/tex], divide both sides of the equation by 4:
[tex]\[
x = \frac{124}{4}
\][/tex]
3. Perform the division on the right-hand side:
[tex]\[
x = 31
\][/tex]
Therefore, the solution to the equation [tex]\( 4x = 124 \)[/tex] is [tex]\( x = 31 \)[/tex].
So, the correct answer is:
B. [tex]\( x = 31 \)[/tex]
