It seems that you would first subtract the "+1" from both sides. this would yield the equation: 2x= 16. Then, you divide both sides by "2" in an effort to isolate the variable, "x". You are then left with x=8. seeing as 16 divided by 2= 8.

-2x plus 3y equals 1
NM equals 2x + 1, as stated in the question!
The answer to 1 over 2x plus 13 equals 9 is x equals -8.
x equals 4
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
