5m+2j=15000 5j+3m=12000 Maka 1m+1j=

eliminasi

5m+2j = 15000   |x5|   25m+10j=75000

5j+3m = 12000   |x2|   10j + 6m= 24000

                                   -----------------------  -

                                            19m= 52

                                                m = 52 / 19 = 2,68

substitusi

5m+2j = 15000

5. (2,68) + 2j=15000

13,4 + 2j = 15000

2j = 15000 - 13,4

j = 14986,6 / 2

j = 7493,3

jadi 1m+1j = 2,68 + 7493,3 =  7495,98
