Question

Solve 3x+y=8, x+y=4 by elimination method

Answer 1

Question : -

3x + y = 8

x + y = 4

Solve by elimination method

Solution : -

3x + y = 8

x + y = 4

-. -. -.

__________

=> 2x = 4

=> x = 4/2 = 2

Putting the value of x in equation (ii)

x + y = 4

=> 2 + y = 4

=> y = 4-2 = 2

$\large{\boxed{\bf{x=2}}}$

$\large{\boxed{\bf{</p><p>y=2}}}$
