Question 338315
I'll do the first one to get you started.




{{{-3x+7=x-1}}} Start with the given equation.



{{{-3x=x-1-7}}} Subtract {{{7}}} from both sides.



{{{-3x-x=-1-7}}} Subtract {{{x}}} from both sides.



{{{-4x=-1-7}}} Combine like terms on the left side.



{{{-4x=-8}}} Combine like terms on the right side.



{{{x=(-8)/(-4)}}} Divide both sides by {{{-4}}} to isolate {{{x}}}.



{{{x=2}}} Reduce.

Answer:


So the solution is {{{x=2}}}
