Answer:

x=14

Step-by-step explanation:

Step 1: Subtract 6 from both sides.

21x+6−6=300−6

21x=294

Step 2: Divide both sides by 21.

21x

21

=

294

21

x=14

Answer: X = 14



Explain:

21 x + 6 = 300

** Switch 6 and 300 **

21 x = 300 - 6

** The reason the plus sign is switched with the subtraction is because a positive will always be a negative & vice versa **

Subtract/take away

300 - 6

21x = 294

21 21 **divide**


**Now divide both sides by 21**

And you’ll get 14

X = 14

Hopefully this helps :)
