Determine which equations are linear equations in the variables x, y, and z. If any equation is not linear, explain w hy not.
Determine which equations are linear equations in the variables x, y, and z. If any equation is not linear, explain w hy not.
Step 1
Consider the given equation
Step 2
Coefficient of x is 1, that of y is -π, and that of z is
Since all these coefficients are constant
Thus, it can be concluded that the given equation
