Question 843416
{{{14x-20y=48}}}
1.{{{7x-10y=24}}}
{{{4x-12y=-24}}}
2.{{{x-3y=-6}}}
Multiply eq. 2 by -7 and add to eq. 2 to eliminate {{{x}}},
{{{7x-10y-7x+21y=24+42}}}
{{{11y=66}}}
{{{highlight(y=6)}}}
Then use either equation to solve for {{{x}}}
{{{x-3(6)=-6}}}
{{{x=18-6}}}
{{{highlight(x=12)}}}
