Answer :

To solve the equation [tex]\(5x = 140\)[/tex], follow these steps:

1. Identify the equation:
The given equation is [tex]\(5x = 140\)[/tex].

2. Isolate the variable [tex]\(x\)[/tex]:
To isolate [tex]\(x\)[/tex], you need to divide both sides of the equation by 5.

[tex]\[ x = \frac{140}{5} \][/tex]

3. Perform the division:
Calculate [tex]\(\frac{140}{5}\)[/tex]:

[tex]\[ x = 28 \][/tex]

Therefore, the solution to the equation [tex]\(5x = 140\)[/tex] is [tex]\(x = 28\)[/tex].

The correct answer is [tex]\( \boxed{D} \)[/tex].
