here,
15x + 40/3 -25 = 0
= >15x + (40 -125)/3 =0
=> 15x + (-85/3) = 0
=> 15x = 85/3
=> x = 85/ (3×15)
=> x = 17/15
hence, x = 17/15 so, putting the value of x in equation.
9x + 8y = 15
9(17/ 15) + 8y = 15
=> 51/5 +8y =15
=> 8y = 15 -51/5
=> 8y = (75 -51)/5
=> 8y = 24/5
=> y = 24/(5×8)
=> y = 3/5
so,
x = 17/15 and y = 3/5
