This Letter reports on the detection of two new multiple planet systems around solar-like stars HD 47186 and HD 181433. The first system includes a hot Neptune of 22.78M_{Earth}_ at 4.08-days period and a Saturn of 0.35M_{Jup}_ at 3.7-years period. The second system includes a Super-Earth of 7.5M_{Earth}_ at 9.4-days period, a 0.64M_{Jup}_ at 2.6-years period as well as a third companion of 0.54M_{Jup}_ with a period of about 6 years. These detections increase to 20 the number of close-in low-mass exoplanets (below 0.1M_Jup_) and strengthen the fact that 80% of these planets are in a multiple planetary systems.
