Question 842130
No, {{{x}}} should be {{{-2}}}.
Multiply eq. 1 by 3 and eq. 4 by 3 and add them.
{{{3(3x+4y)+4(2x-3y)=3(14)+4(-19)}}}
{{{9x+12y+8x-12y=42-76}}}
{{{17x=-34}}}
{{{x=-2}}}
You just use either equation to solve for {{{y}}}.
{{{3x+4y=14}}}
{{{3(-2)+4y=14}}}
{{{-6+4y=14}}}
{{{4y=20}}}
{{{y=5}}}
