9x-10y=-12 -eq.1 2x+3y=13 -eq.2 Lets take eq2 2x+3y=13 2x=13-3y X=13-3y/2 eq 3 Now let's place the value of x from eq 3 to eq 1 9x-10y=-12 9(13-3y/2)-10y=-12 117-27y-20y=-24 47y=-24-117 47y=141 Y=141/47 Y=3 -eq4 Putting the value of y through eq4 in eq2 2x+3y=13 2x+3(3)=13 2x+9=13 2x=13-9 2x=4 X=4/2 X=2 - eq5 Hence from equation 4 and 5 we can say that the value of x=2 and the value of y=3 - Hence proved Hope it helps
