Question

solve the following pair of linear equation by the elimination method x+y=5,2x-y=4​

Answer 1

x + y = 5......(1)

2x – y = 4.......(2)

Add equation (1) and (2)

x + y = 5

2x – y = 4

------------

3x = 9

x = 9 / 3

x = 3

Put x = 3 in equation (1)

3 + y = 5

y = 5 – 3

y = 2

(x,y) = (3,2) is the solution of given simultaneous equation.
