hey guys, i need help rearranging this circuit!
tried a few ways but when i figure out the total resistance it doesnt correspond with the answer :(

start of with the right hand side, the 10 and 30 ohm resistors are in parellel with the 5 ohm in series. find the effective resistance of these 3 resistors. redrwa the circuit the the 3 resistors replaced as 1 in parallel with the other 30 ohm and in series with the 40 ohm.
