Question 343016
{{{7-(2x-1)=10}}}
{{{-(2x-1)=3}}}
{{{2x-1=-3}}}
{{{2x=-2}}}
{{{highlight(x=-1)}}}
.
.
.
{{{3/x-1/3=1/6}}}
Multiply both sides by {{{6x}}}
{{{18-2x=x}}}
{{{3x=18}}}
{{{highlight(x=6)}}}
.
.
.
{{{(x+7)(x-1)=(x+1)^2}}}
Use the FOIL method,
{{{x^2-x+7x-7=x^2+x+x+1}}}
{{{x^2+6x-7=x^2+2x+1}}}
{{{4x=8}}}
{{{highlight(x=2)}}}
