Question 1205723


{{{6x+2y=34}}}......eq.1
{{{x=-4y+24}}}.....eq.2

-----------------------------------

substitute {{{x}}} from eq.2 in eq.1

{{{6(-4y+24)+2y=34}}}......eq.1, solve for {{{y}}}

{{{-24y+144+2y=34}}}

{{{-22y+144=34}}}

{{{144-34=22y}}}

{{{110=22y}}}

{{{y=110/22}}}

{{{y=5}}}

go to eq.2, substitute {{{y}}}

{{{x=-4*5+24}}}.....eq.2

{{{x=-20+24}}}

{{{x=4}}}


A. One solution:{{{x=4}}},{{{y=5}}}
