Solve for x and y 37x 43y 123 43x 37y 117?

Answer 1

7x+43y=123 ..............(1)

43x+37y=117 ..............(2)

ADD EQN (1)AND(2)

WE GET 80X + 80Y = 240, WHICH WHEN REDUCED IS X + Y = 3 ........................(3)

SUBRACTING EQN (1) AND (2) WE GET

-6X + 6Y = 6, WHICH WHEN REDUCED IS (-X + Y = 1) ........................(4)

ADDING EQN (3) AND (4)

X + Y = 3

-X + Y = 1

WE GET 2Y = 4

SO Y = 2

SUBSTITUTING Y = 2 IN EQN (3) WE GET

X + 2 = 3

SO X = 1

THEREFORE X= 1 AND Y = 2 IS THE SOLUTION FOR THE PAIR OF LINEAR EQUATIONS.

Answer 2

123
