Answer: identity
Explanation:
Given The equation:
0.3(x + 3) - 0.6(x + 3) = -0.3x -0.9
Selecting the left hand side :
0.3(x + 3) - 0.6(x + 3)
= 0.3x + 0.9 - 0.6x - 1.8
= 0.3x - 0.6x + 0.9 - 1.8
= - 0.3x - 0.9
Solving the left hand side, we obtain the same expression stated on the right hand side.
Hence the expression is an identity
Since,
L. H. S = R. H. S
