Question 337624
1.{{{8x + 7y = -16 }}}
2.{{{6x - 3y = -12}}}
Multiply eq. 1 by 3 and eq. 2 by 7 and add them to eliminate {{{y}}}.
{{{24x+21y+42x-21y=-48-84}}}
{{{66x=132}}}
{{{highlight(x=2)}}}
.
.
.
Now use either equation to solve for {{{y}}}.
{{{6(2)-3y=-12}}}
{{{12-3y=-12}}}
{{{-3y=-24}}}
{{{highlight(y=8)}}}
