Question 695244

{{{2(10+7x)=-36}}} Start with the given equation.



{{{20+14x=-36}}} Distribute.



{{{14x=-36-20}}} Subtract {{{20}}} from both sides.



{{{14x=-56}}} Combine like terms on the right side.



{{{x=(-56)/(14)}}} Divide both sides by {{{14}}} to isolate {{{x}}}.



{{{x=-4}}} Reduce.

Answer:


So the solution is {{{x=-4}}} 




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


{{{-79=-5x-4x+2}}} Start with the given equation.



{{{-79=-9x+2}}} Combine like terms on the right side.



{{{0=-9x+2+79}}} Add {{{79}}} to both sides.



{{{9x=2+79}}} Add {{{9x}}} to both sides.



{{{9x=81}}} Combine like terms on the right side.



{{{x=(81)/(9)}}} Divide both sides by {{{9}}} to isolate {{{x}}}.



{{{x=9}}} Reduce.

Answer:


So the solution is {{{x=9}}}
