HOW TO SOLVE X & Y LINEAR EQUATION PROBLEMS???
Let us consider this following equation 8x+5y=9 3x+2y=4 Solving this on traditional method will take more time… so here, we are solving it in cross multiplication method.. For this, 1 st check whether the equation is in the correct order.. Eg It must be in Ax+By=c1…..(1) Dx+Ey=c2…..(2) here, a,b,c1,d,e,c2 are any numbers.. Then 2 nd step is taking coefficient of y from equation 2 is necessary.. always start with that number . Ax+ By=c1 Dx+ Ey=c2 for getting numerator part first consider this highlighted part and start with E, ie. Coefficient of y in 2 nd equation And subtract those terms… E*C1 – C2*B this is numerator part . For getting denominator part Ax+By =c1…..(1) Dx+Ey =c2…..(2) Consider this highlighted part & again start with E i.e. Coefficient of y in 2 nd equation. And subtract those terms E*A – D*B this denominator part Numerator part / denominator part E*C1 – C2*B/ E*A – D*B Solving this we ...
