Question 201980


{{{2x-(4x+2)+7=-9x-5}}} Start with the given equation.



{{{2x-4x-2+7=-9x-5}}} Distribute.



{{{-2x+5=-9x-5}}} Combine like terms on the left side.



{{{-2x=-9x-5-5}}} Subtract {{{5}}} from both sides.



{{{-2x+9x=-5-5}}} Add {{{9x}}} to both sides.



{{{7x=-5-5}}} Combine like terms on the left side.



{{{7x=-10}}} Combine like terms on the right side.



{{{x=(-10)/(7)}}} Divide both sides by {{{7}}} to isolate {{{x}}}.

Answer:


So the solution is {{{x=-10/7}}} which approximates to {{{x=-1.429}}}.
