C-12-Q049mediumsingle_mcqThe solution of 5x+4y=10, 4x+5y=85x + 4y = 10,\; 4x + 5y = 85x+4y=10,4x+5y=8 is —a(2,0)(2, 0)(2,0)b(0,2)(0, 2)(0,2)c(2,2)(2, 2)(2,2)d(1,1)(1, 1)(1,1)ব্যাখ্যাSubstituting (2,0)(2, 0)(2,0): 5(2)+4(0)=105(2) + 4(0) = 105(2)+4(0)=10 ✓ and 4(2)+5(0)=84(2) + 5(0) = 84(2)+5(0)=8 ✓. Both equations hold, confirming (2,0)(2, 0)(2,0).
