Question 480044
{{{system(y = x + 5 , x + y = -2)}}}
I think better to use the substitute method
substitute {{{y=x+5}}} into the second equation
{{{x+x+5=-2}}}
{{{2x=-2-5}}}
{{{2x=-7}}}
{{{x=-7/2}}}
{{{x=-3.5}}} substitute into the first equation of the system
{{{y=-3.5+5}}}
{{{y=1.5}}}
Answer (-3.5,1.5)
