Question 71012
5x - 2y = -5
 y - 5x = 3
First you need to solve one of the equations for either x or y, since y is already by itself in the second equation llets solve that one for y;
y-5x=3
add -5x to both sides;
y=3+5x
Now but this equation in place of the y in the first equation;
5x - 2(3+5x)=-5
distribute the 2;
5x-6-10x=-5
-6-5x=-5
add 6 to both sides;
-5x=-5+6
-5x=1
divide each side by -5;
{{{-5x/-5}}}={{{1/-5}}}
x=-{{{1/5}}}
now plug that in for x in either equation, we will go ahead and usethe first again;
5({{{-1/5}}}) - 2y = -5
{{{-5/5}}}-2y=-5
-1-2y=-5
add 1 to both sides;
-1-2y+1=-5+1
-2y=-4
divide each side by -2
y={{{-4/-2}}}
y=2
so you have;
x={{{-1/5}}}
y=2
