(2) y=-5x+6
3x-4y=-24
Rewrite the second as
-4y=-3x-24 or as y=(3/4)x+6
They are now both in slope-intercept form with the same intercept (0,6), their solution.
 
As for (1) it is given as
(1) 4x+2y=-8
y=3/4+7
 
I am going to assume you meant
4x+2y=-8
y=(3/4)x+7
Now we rewrite as
4x+2y=-8
(3/4)x-y=-7
 
Divide the first equation by 2 and have
2x     +y=-4
(3/4)x-y=-7
Add and get (2 3/4)x=-11 or (11/4)x=-11 or x=-4
and -16+2y=-8 gives y=4
(3/4)(-4)-4=-7
