Question 769576

{{{-3x-3y=3}}}..eq.1 and 
{{{y=-5x-17}}}...eq.2
___________________substitute {{{y}}} in eq.1 

{{{-3x-3(-5x-17)=3}}}..eq.1 .......solve for {{{x}}}

{{{-3x+15x+51=3}}}

{{{12x=3-51}}}

{{{12x=-48}}}

{{{x=-48/12}}}

{{{x=-4}}}

now find {{{y}}}

{{{y=-5x-17}}}...eq.2

{{{y=-5(-4)-17}}}

{{{y=20-17}}}

{{{y=3}}}
