Question 897381
{{{x^2-2x-48=0}}}
{{{(x-8)(x+6)=0}}}
{{{x=8}}} and {{{x=-6}}}
.
.
.
Subtract,
{{{4x+5y-2x-5y=61-43}}}
{{{2x=18}}}
{{{x=9}}}
Then,
{{{4(9)+5y=61}}}
{{{36+5y=61}}}
{{{5y=25}}}
{{{y=5}}}
.
.
.
{{{x^2+5x-24=0}}}
{{{(x+8)(x-3)=0}}}
{{{x=-8}}} and {{{x=3}}}
.
.
.
Simplify eq. 2,
{{{-x+y=0}}}
{{{y=x}}}
Substitute,
{{{4x+x=10}}}
{{{5x=10}}}
{{{x=2}}}
{{{y=2}}}
