Answer:
y = x + 3/5
Step-by-step explanation:
1. Label this function 'y': y = x - 3/5
2. Interchange x and y: x = y - 3/5
3. Solve this for y: y = x + 3/5
This last result is the inverse of the given function.

1st, change 15 & one third into improper fraction

Then Multiply them

= 184

Answer:
x = 3
Step-by-step explanation:
Multiply the first equation by -1, then add it to second equation.
2x+9y = -12
-2x-7y = 8
-------------------
2y = -4
Solve for y
2y = -4
y = -2
Plug value of y into one of the equations and solve for x
2x + 9(-2) = -12
2x = 6
x = 3
