Hello from MrBillDoesMath!
Answer:   x = 7/10
Discussion:
To eliminate fractions multiply each side by 10:
10 ( 9/5x - 2/5 )  = 10 * ( 8x +3)/10      or
10 * ( 9/5)x - 10 *(2/5)  =   8x + 3  or
9 *2 x - 2*2 = 8x +3   or
18x - 4 = 8x + 3.  Subtract 8x for each side:
18x - 8x - 4 = (8x - 8x) + 3 or
10x -4 =  0x + 3 or
10x -4 = 3 or
10x = 7
x = 7/10
Thank you,

Answer:
No, every relation is not a function.   
Step-by-step explanation:
Every function is a relation because there are two points (x,y) somehow related to each other.
But every relation is not a function
The given ordered pairs are the function 
Since, we are getting different value of y for ecah x.
The condition for function is we should get different value of y for each x.
