Please can someone solve x and I need it as an improper fraction please ​

7x=21/5

X=3/5

hope it helps

x=26/7

Step-by-step explanation:

Add 5/7 to both sides. Multiply 3 and the denominator being 7 to get 21. Add the numerator of 5 to 21 to get 26. The denominator stays the same and the numerator becomes 26.

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'.
