8 - 8 / (5-3) =
8 - 8/2 =
8-4 =
4

can anyone help me solve this i am having anxiety over this

7x-3y+2z=0
4x-4y-z=2
5x+2y+3z=1

if you can show work that would be great

8 - 8 / (5 - 3) = 4

Use GauB

Gauss elimination. Just google it

>>7921798
x =1
y=1
z=-2

subtract equations to eliminate variables.

instead of wasting time writing out the equations you should do it as a matrix and solve by rref

The order doesn't matter, as long as things cancel out
