Please show work for these, thank you! 
A circuit is constructed with six resistors and two batteries as shown. The battery voltages are V1=18 V and V2=12 V. The positive terminals are indicated with a + sign, The values for the resistors are: R1=R5=59Ω,R2=R6=130ΩR3=48Ω, and R4=129Ω. The positive directions for the currents I1,I2 and I3 are indicated by the directions of the arrows. 1) What is V4, the magnitude of the voltage across the resistor R4 ?
4) What is I1, the current that flows through the resistor R1 ? A positive value for the current is defined to be in the direction of the arrow. 4 5) What is V(a)−V(b), the potential difference between the points a and b ?
