Question

Solve the pair of equations by using the substitution method.
√2x + √3y = 0
√3x - √8y = 0

Answer 1

Hi ,

It is given that,

√2x + √3y = 0

=> x = ( -√3/√2 )y---( 1 )

√3x - √8y = 0 -----( 2 )

Substitute equation ( 1 ) in equation ( 2 ),

we get

=>√3( -√3/√2)y - √8y = 0

=> (-3/√2 )y - √8y = 0

y = 0

substitute y = 0 in equation ( 1 ),

we get

x = ( - √3/√2 )× 0

x = 0

Therefore ,

x = 0 , y = 0

I hope this helps you.
