Question

root 2x + root 3y = 0 and root 3 x minus root 8 Y = 0 by elimination method

√2x+√3y=0,√3x-√8y=0 solve by elimination method.

Answer 1

√2x + √3y = 0 ------- (1)

√3x - √8y = 0 ------- (2)

Multiply eqn 1 with √8

We get,

4x + 2√6y = 0 ------ (3)

Multiply eqn 2 with √3

We get,

3x - 2√6y = 0 ------ (4)

Add eqn (3) & (4)

We get,

4x + 2√6y = 0 +
3x - 2√6y = 0
--------------------
7x = 0

Therefore x = 0

Substituting x in any above eqn we will get y = 0.
