1) 15+6 = 21.
21 in parallel with 7.3, = (21 x 7.3)/(21 + 7.3) = 5.417ohms.
5.417 + 12 = 17.417 ohms equivalent circuit resistance.
Circuit current = (18/17.417) = 1.0335A.
R1 will have 1.0335A through it.
V drop across R1 = (1.0335 x 12) = 12.402V.
18 - 12.402 = 5.598V across R3, also R2 and R4 in series.
R3 will have (5.598/7.3) = .767A through it.
R2 and R4 will both have (5.598/21) = .,2666A through them.
2) You can do that.
