Question 181299
well lets hope I do the equation the way it is suppose to be
:
your just plugging in the value of -1 into the variable y and checking to see if this makes a true or false statement
:
{{{4^2-1=4y+3}}}
:
{{{16-1=4(-1)+3}}}
:
{{{15=-4+3}}}
:
{{{15<>-1}}} since 15 does not equal -1.....-1 is NOT a solution. If the equation is different that this email me the correct equation..thanks Mathtut
