Question 1091063


{{{-7 (1-8x)+2=-5-x}}}

step 1: multiply {{{-7 (1-8x)}}}

{{{-7*1-7(-8x)+2=-5-x}}}

{{{-7+56x+2=-5-x}}}

step 2: add {{{-7}}}and {{{2}}}(it gives you {{{-5}}}), and {{{x}}} to both sides

{{{-5+56x+x=-5-x+x}}}

{{{-5+57x=-5}}}

step 3: add {{{5}}} to both sides

{{{-5+5+57x=-5+5}}}

{{{0+57x=0}}}

{{{57x=0}}} it is true only if

{{{x=0}}}
