Question 222851
{{{abs(7x-4)-4=-11}}} Start with the given equation



{{{abs(7x-4)=-7}}} Add 4 to both sides.



Since the equation {{{abs(7x-4)=-7}}} is <font size=4><b>never</b></font> true (note: remember, the absolute value of any number is <font size=4><b>always positive</b></font>), there are no solutions to {{{abs(7x-4)=-7}}}



This means that there are no solutions to the equation {{{abs(7x-4)-4=-11}}}
