What is 1/2 ( 3/5x - 8) + 7/4 ( 2/5x + 4)? (simplify the expression by distributing and combining like terms)

(1/2)*((3/5)*x-8)+(7/4)*((2/5)*x+4) = 0

1/2*(3/5*x-8)+7/4*(2/5*x+4) = 0

1/2*(3/5*x-8)+7/4*(2/5*x+4) = 0

x+3 = 0

x+3 = 0

x+3 = 0 // - 3

x = -3

x = -3

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
