Question 878473
{{{(x+8)/7=(3-5y)/4}}}
Multiply both sides by {{{7*4}}}
{{{4(x+8)=7(3-5y)}}}
{{{4x+32=21-35y}}}
1.{{{4x+35y=-11}}}
.
.
.

{{{(3x)/5=(27-9y)/10}}}
Multiply both sides by {{{10}}}
{{{6x=27-9y}}}
{{{6x+9y=27}}}
2.{{{2x+3y=9}}}
Multiply eq. 2 by (2) and subtract from eq. 1,
{{{4x+35y-4x-6y=-11-18}}}
{{{29y=-29}}}
{{{highlight(y=-1)}}}
Then,
{{{2x+3(-1)=9}}}
{{{2x=12}}}
{{{highlight(x=6)}}}
