It's 21.125 hope this works good luck ;)
Answer:
the answer C
Step-by-step explanation:
What you can do is subtract 1x from each side
Then you subtract 3 from each side
Then it tells you x=2
Always put what you think x is back into the problem and see if it works out
Example on how you do it:
(x+5)=(2x+3)
5=(x+3)
2=x
Hope this helps let me know if it does :)
