To solve the equation [tex]\( 5x = 140 \)[/tex] for [tex]\( x \)[/tex], follow these steps:
1. Start with the given equation:
[tex]\[
5x = 140
\][/tex]
2. To isolate [tex]\( x \)[/tex], divide both sides of the equation by 5. This can be written as:
[tex]\[
x = \frac{140}{5}
\][/tex]
3. Perform the division on the right-hand side:
[tex]\[
x = 28
\][/tex]
So, the solution to the equation [tex]\( 5x = 140 \)[/tex] is [tex]\( x = 28 \)[/tex].
Thus, the correct answer is:
B. [tex]\( x = 28 \)[/tex]
