Question 158917
{{{5x-10=-7x+1}}}
.
{{{5x+7x=10+1}}}, combine similar terms
{{{12x=11}}}, add or subtract
{{{cross(12)x/cross(12)=11/12}}}, divide 12 to isolate "x"
{{{x=11/12}}} -----------------> ANSWER
Check by substitution:
{{{5(11/12)-10=-7(11/12)+1}}}
{{{(55/12)-10=-77/12+1}}}
{{{(55-120)/12=(-77+12)/12}}}
{{{-65/12=-65/12}}}
Thank you,
