For this ti be solve, lets factor in some alphabets to represent some numbers in the equations 6/3j + 4/6k = 10 -2/j +3/k = -7

Let a=1/j and b=1/k then:

(6/3)a+(4/6)b=10, - 2a+3b= -7, so a=3b +7/2

Substitute for a in the other equation:

(6/3)(3b +7/2)+(4/6)b=10

6(3b +7)/6 + 4b = 60

18b + 42/6 +4b = 60
