Question

Urgent please solve

solve the pair of equation ; 1)

43x +67y = -24
67x + 43y = 24
​

Answer 1

X+y=0

Step-by-step explanation:

(43x+67y=-24)+(67x+43y)= -24+24 =0

110x +110y=0

110(x+y) =0

(x+y)=0/110.

X+y=,0

Answer 2

let 43x + 67y = -24 be 1st equation and

67x + 43y = 24 be 2nd equation.

multiply 67 in equation 1st. and

multiply 43 in equation 2nd

67(43x + 67y)= -24*67

43(67x+43y) = 24*4

2881x + 4484y = -1608________ 3rd equation

2881x + 1848y = 1032________4th equation

Subtracting equation 4th from equation 3rd.

2881x + 4484y = -1608

2881x + 1848y = 1032

-. -. -

____________________

2636y= -2640

y= -2640/2636

y = -660/659

putting value of y in equation 1s equation
