Question 150801
*[Tex \LARGE 3\left\[7 - \left(7x - 4\right)\right\] + 6x = 0] Start with the given equation.



*[Tex \LARGE 3\left\(7\right) - 3\left(7x - 4\right) + 6x = 0] Distribute




*[Tex \LARGE 21 - 3\left(7x - 4\right) + 6x = 0] Multiply 3 and 7 to get 21



{{{21-21x+12+6x=0}}} Distribute.



{{{-15x+33=0}}} Combine like terms on the left side.



{{{-15x=0-33}}} Subtract {{{33}}} from both sides.



{{{-15x=-33}}} Combine like terms on the right side.



{{{x=(-33)/(-15)}}} Divide both sides by {{{-15}}} to isolate {{{x}}}.



{{{x=11/5}}} Reduce.

Answer:


So the answer is {{{x=11/5}}} 



Which approximates to {{{x=2.2}}}
