Question 351492
1.{{{(1/3)x + (1/2)y = -3}}}
2.{{{(1/3)x + 3y = -13}}}
Subtract eq. 1 from eq. 2 to eliminate {{{x}}}.
{{{(1/3)x+3y-(1/3)x-(1/2)y=-13-(-3)}}}
{{{(5/2)y=-10}}}
{{{highlight(y=-4)}}}
Then use either equation to solve for {{{x}}}
{{{(1/3)x-12=-13}}}
{{{(1/3)x=-1}}}
{{{highlight(x=-3)}}}
