Question

Solve the Following simultenous Linear equation using substitution method.​

Answer 1

Answer:

1) (a) x = 6, y = 1.

Step-by-step explanation:

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

x + y = 7....( 2 )

( Cut + y and - y ),

We get,

=》2x = 12

=》x = 12 / 2

=》x = 6.

( Putting the value of x in ( 1 ),

x - y = 5

=》6 - y = 5

=》- y = 5 - 6

=》- y = - 1 ( Cut - and - )

=》y = 1.
