What is the solution to this equation?

[tex]\[ 5x = 140 \][/tex]

A. [tex]\( x = 135 \)[/tex]

B. [tex]\( x = 28 \)[/tex]

C. [tex]\( x = 700 \)[/tex]

D. [tex]\( x = 14 \)[/tex]


Sagot :

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]
