Question 161695
I'll do the first one to get you started





{{{2(3+7x)-(1+15x)=2}}} Start with the given equation.



{{{6+14x-1-15x=2}}} Distribute.



{{{-x+5=2}}} Combine like terms on the left side.



{{{-x=2-5}}} Subtract {{{5}}} from both sides.



{{{-x=-3}}} Combine like terms on the right side.



{{{x=(-3)/(-1)}}} Divide both sides by {{{-1}}} to isolate {{{x}}}.



{{{x=3}}} Reduce.

Answer:


So the answer is {{{x=3}}}
