Question

solve the Pair of linear equation....
x+5y=9
x+3y=5
solve it fast​

Answer 1

Answer:

x+5y=9_________(1)

x+3y=5_________(2)

from eq. no. 1 ,

X= 9-5y________(3)

Putting the value of X in the equation no. (2),

we get,

9-5y+3y=5

=>2y= 4

=>y = 2

After putting the value of y in the equation no. 3 ,.

x=-1

Here,. X= -1. &. y= 2

Answer 2

Given :  x + 5y = 9

x + 3y = 5

To Find : Value of x & y

Solution:

x + 5y = 9       Eq1

x + 3y = 5       Eq2

Eq1 - Eq2

=> 2y = 4

=> y = 2

Substitute y = 2 in Eq1

=> x + 5(2) = 9

=> x + 10 = 9

=> x = - 1

x = - 1  ,   y  = 2

Verification

x + 5y = 9

-1 + 5(2) = -1 + 10 = 9

x + 3y = 5

=> - 1 + 3(2) = -1 + 6  =  5

x = - 1  ,   y  = 2
