To graph the equations, it is best to get them into slope-intercept form.
.
3x -4y = 32
-4y = -3x +32
y = 3/4*x -8
.
(0,-8)
(32/3,0)
.
5x +2y = 10
2y = -5x +10
y = -5/2*x +5
.
(0,5)
(2,0)
.

.
To check, you can solve the system of equations.
.
3x -4y = 32
5x +2y = 10
.
Multiply the second equation by 2 and then add them.
.
3x -4y = 32
10x +4y = 20
-------------- add
13x = 52
x = 52/13 = 4
.
3(4)-4y = 32
-4y = 20
y =-5
.
5(4) +2(-5) = 10 ??
20 -10 = 10
Correct.
.
So, the lines intersect at (4,-5). You can check the graph to see if this is correct.
