Question

solve the system of equation -2x+15y=-24 -24+9y=24​

Answer 1

Answer:

x=32/19, y=104/57

Step-by-step explanation:

-24x+9y =-24 ---- equation-1

-2x+15y=24

=(-2x+15y=24)12

=-24x+180y=288 ---------- equation-2

Difference of equation-1 from equation-2

-24x+180y=288

-24x+9y    =-24

        171y= 48

y=312/171

y= 104/57

Substituting y in equation-1

-24x+9*104/57=-24

=(-24*57x+936)/57=-24

=-1368x+936=-24*57

=-1368x+936=-1368

=-1368x=-1368-936

=-1368x=-2304

=1368x=2304

x=2304/1368

x=32/19
