Question 114199

{{{-5-2(3x-4)=21}}} Start with the given equation




{{{-5-6x+8=21}}} Distribute



{{{-6x+3=21}}} Combine like terms on the left side



{{{-6x=21-3}}}Subtract 3 from both sides



{{{-6x=18}}} Combine like terms on the right side



{{{x=(18)/(-6)}}} Divide both sides by -6 to isolate x




{{{x=-3}}} Divide

Answer:

So our answer is {{{x=-3}}}
