Hi guys,

I really need some help with this problem, along with working.

I have done heaps of these but this one keeps giving me issues:

2x+5y+3z = 16

x/5+y/2+z/3=2

3x-2y-4z=-2

solve for x,y,z

Im still confused. I learnt how to do this a different way. anyone willing to give me whole solution so I can learn?

Hello, do you know how to solve a matrix? I solved the equations. Do you want me to reveal the solution?

Well I'm not allowed to post the solution. Try to solve it with matrix. You have to make 4 matrices with the coefficients of unknown variables.

Use D (determinants)
