Question

solve the pair of linear equation 2x+y=12 and x-y=3 by elimination method​

Answer 1

Answer:

$b y \: elemination \: method \: the \: value \: of \: x = 2 \: and \: y = 2$

Answer 2

Answer:

2x + y = 12. (1)

x - y = 3. (2)

adding above equation

3x = 15

x = 15/3

x = 5

putting value of x in equation (1)

2(5)+y = 12

y = 12-10

y = 2

x = 5 & y = 2
