Question 1134397
{{{3x + y = -26}}}....eq.1
{{{2x - y = -19}}}....eq.2
----------------------------------add both

{{{3x + y +2x - y = -26-19}}}

{{{3x + cross(y) +2x - cross(y) = -26-19}}}

{{{3x  +2x  = -45}}}

{{{5x  = -45}}}

{{{x  = -45/5}}}

{{{highlight(x  = -9)}}}


go to {{{3x + y = -26}}}....eq.1, plug in {{{x}}} value

{{{3(-9) + y = -26}}}....solve for {{{y}}}

{{{-27 + y = -26}}}

{{{ y = 27-26}}}

{{{ highlight(y = 1)}}}


solution: intersection point at ({{{ -9}}},{{{ 1}}})


{{{ graph( 600, 600, -15, 10, -10, 10, -3x-26, 2x+19) }}}
