Answer:
J-¹(x)= x+6/5
or
J-¹(x)= x/5 + 6/5
Explanation:
J(x)= 5x -6
•first separate your Y from the original equation like this
y= 5x-6
•second replace for x since we are talking about the inverse form
x= 5y-6
•third solve for y
x+6=5y-6+6
add 6 to both sides
x+6=5y
divide 5 to both sides
x+6/5=5y/5 (in your right side 5 cancels out)
it should look like this
x+6/5=y (you solved for y)
and now you write your answer like this
J-¹(x)= x+6/5
or
J-¹(x)= x/5 + 6/5
