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
I'd start by multiplying all of the second equation by 5. This will give a single x term. Then make this equation the first row, and it will make eliminating the other x values quite easy. See what you can do.
