Eq1: `2x+3y=0`
Eq2:`4x+3y-z=0`
Eq3:`8x+3y+3z=0`
Multiply equation 2 by 3,
`12x+9y-3z=0`
Now add the above equation and equation 3,
`(8x+3y+3z)+(12x+9y-3z)=0`
`8x+12x+3y+9y+3z-3z=0`
`20x+12y=0`
`4(5x+3y)=0`
`5x+3y=0`
Now let's solve the above equation and equation 1,
`2x+3y=0`
`5x+3y=0`
Subtract the above equations
`2x-5x=0`
`-3x=0`
`x=0`
Substitute back the value of x,
`2x+3y=0`
`2(0)+3y=0`
`3y=0`
`y=0`
Plug in the value of x and y in equation 2,
`4(0)+3(0)-z=0` ` `
`-z=0`
`z=0`
Solutions of the equations are x=0, y=0 and z=0
