Question 374484
I'll do the first two to get you started.


# 1


{{{17x-42=-39}}} Start with the given equation.



{{{17x=-39+42}}} Add {{{42}}} to both sides.



{{{17x=3}}} Combine like terms on the right side.



{{{x=(3)/(17)}}} Divide both sides by {{{17}}} to isolate {{{x}}}.



--------------------


Answer:


So the solution is {{{x=3/17}}} 


=======================================================================

# 2


{{{7x-2=5x+10}}} Start with the given equation.



{{{7x=5x+10+2}}} Add {{{2}}} to both sides.



{{{7x-5x=10+2}}} Subtract {{{5x}}} from both sides.



{{{2x=10+2}}} Combine like terms on the left side.



{{{2x=12}}} Combine like terms on the right side.



{{{x=(12)/(2)}}} Divide both sides by {{{2}}} to isolate {{{x}}}.



{{{x=6}}} Reduce.



-------------------


Answer:


So the solution is {{{x=6}}}
