Problems Delta to Wye conversion

I have a circuit like this. And, I want to calculate resistance from here. I was following these steps. I was calculating resistance for left side circuit. $$R_1=\frac{2 × 2}{2+2+4}=0.5\Omega$$...

Delta to Wye conversion
[![enter image description here][1]][1]

I have a circuit like this. I was following these [steps](https://www.allaboutcircuits.com/textbook/direct-current/chpt-10/delta-y-and-y-conversions/).

I was calculating resistance for left side circuit. 

$$R_1=\frac{2 × 2}{2+2+4}=0.5\Omega$$
$$R_2=\frac{2 × 4}{2+2+4}=1\Omega$$
$$R_3=\frac{2 × 4}{2+2+4}=1\Omega$$

Then, I took series and parallel circuit. Then, calculated equivalent of resistance.

$$R_s1=0.5+3=3.5$$
$$R_s2=1+3=4$$
$$R_p=(\frac{1}{3.5}+\frac{1}{4})^-1=1.8677$$
$$Requivalent=1.8677+1=2.8667$$

I am not sure if it is correct.
