Good evening student.
1. 2x+5=7
subtract 5 from both sides and simplify
2x-5+5=7-5
the 5's on the left cancel out leaving:
2x=2
divide both sides by 2
2x/2=2/2
the 2's on the left cancel out leaving:
x=1
2. 1/6n+2=9
get rid of the fraction by multiplying both sides by 6
6(1/6n+2)=9x6
the 6's on the left cancel, leaving:
n+12=54
subtract 12 from each side and simplify:
n-12+12=54-12
the 12's on the left cancel leaving:
n=42.

you can check your answer by substituting the values for n and x, if you desire. Thanks for choosing Algebra .com. If you desire paid help, you can contact me @ http://www.prestoexperts.com/expert/marys-tutoring or just click the box
