Question

100 points, please help? explanations are appreciated (: ill give brainliest too

Answer 1

Your answer would be C because 3x-1=26 because -1 and you're solving a math problem -1 would change to positive to cancel out the -1 add 1 to 26 which would be 27 then you would get 3x=27 which would then lead to 3/27 which is 9.

Answer 2

3x = 27 is your answer

The addition of equality states that "if you add on one side, you must add the same number to the other side."

This is true, for you add 1 to each side (doing the opposite of PEMDAS to isolate the x)

C is your answer

Hope this helps
