Question 199086
*[Tex \LARGE 7[2x-4-2(x+1)]=7x+3] ... Start with the given equation.



*[Tex \LARGE 7[2x-4-2x-2]=7x+3] ... Distribute



*[Tex \LARGE 14x-28-14x-14=7x+3] ... Distribute again



{{{-42=7x+3}}} Combine like terms on the left side.



{{{0=7x+3+42}}} Add {{{42}}} to both sides.



{{{0-7x=3+42}}} Subtract {{{7x}}} from both sides.



{{{-7x=3+42}}} Combine like terms on the left side.



{{{-7x=45}}} Combine like terms on the right side.



{{{x=(45)/(-7)}}} Divide both sides by {{{-7}}} to isolate {{{x}}}.



{{{x=-45/7}}} Reduce.

Answer:


So the solution is {{{x=-45/7}}} which approximates to {{{x=-6.429}}}.
