maths question regarding linear algebra

[vanillathunder722]

Hello basically i have to determine whether equations form a linear system or not.
If you take a look at ths equations
4x - y + 2z = -1
-x + (ln2)y - 3z = 0

i would like to know what the (ln2) stand for?

To only time the equations are nonlinear is when the variables are non linear. So, if my math is correct, both are linear

The ln(2) is a log with e as the base instead of 10. You can type in ln(2) on most sci calculators and get an answer. There that is not a variable and does not contribute to determine if the equation is linear or not

If it was ln(x), it would've been nonlinear

Ps. I haven't touched advance maths in years, so take it the advise with caveats

yes it is a linear system end of story

if you spot x^2, x^3...x^n
2^x or ln(x) or sin(x) etc its not linear

ln is Log to base e (Natural logarithm)
