Answer:

mark as brainliest if it helps you dude!!

Answer 2

Step-by-step explanation:

3(x-5)=21

3x-15=21

3x=21+15

3x=36

x=36/3

x=12(by cancelling 3&35 we get 12)

therefore x=12.

(or)

3(x-5)=21

x-5=21/3

x-5=7

x=7+5

x=12

We can use both to solve this equation

verification:

3(12-5)=3*7=21

verification proved that the 12 is the correct answer
