Step 1
Any equation in three variable x, y and z is a linear equation if the equation is in the form of
ax+by+cz+d=0
Where a, b, c and d are constant.
Step 2
Given equation:
3cosx4y+z=3...(1)
Since given equation (1) is not in the form of ax+by+cz+d=0, so given equation is not a linear equation.
Step 3
Hence given equation is not a linear equation.
