Question

Solve for x and y :
i ) 29x +37y =57
37x+29y =82

Answer 1

29x+37y=57____(1)

37x+29y=82________(2)

By elimination method

29(29x+37y=57)

37(37x+29y=82)

841x+1073y=1653

1414x+1073y=3034

-______-________-_____

- 573x=-1381

573x=1381

X=1381/573

X=2.41

Putting the value of X in equation (1)

29(2.41)+37y=57

69.89+37y=57

37y=57-69.89

37y=-12.89

y=-12.89/37

y=-0.34
