Question 698253
{{{21(2-x)+12x=44}}} Start with the given equation.



{{{42-21x+12x=44}}} Distribute.



{{{-9x+42=44}}} Combine like terms on the left side.



{{{-9x=44-42}}} Subtract {{{42}}} from both sides.



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



{{{x=(2)/(-9)}}} Divide both sides by {{{-9}}} to isolate {{{x}}}.



{{{x=-2/9}}} Reduce.

Answer:


So the solution is {{{x=-2/9}}} 


Since -0.22222... is equivalent to {{{-2/9}}}, you have the correct answer.
