As the equation does not consists like terms we can only get x , y equations.

Explanation:

Firstly, they are not like terms.

If the value to be is found is X then,

8x+5y=4

Now subtract 5y on both sides

8x+5y-5y=4-5y

here both positive 5y and negative 5y get cancelled

Now divide by 8

x=(4-5y)/8

If we need y value then,

subtracting both sides by 8x

5y=4-8x

Now dividing with 5 on both sides

y=(4-8x)/5 =>y=4/5 -8x/5

According to Y=mx+c

slope = m = 4/5

y-intercept = -8x/5.
