1. Determine which of the following are linear equations and which are not linear equations. State the reason for your answer.
(a) x + y = 1000
(b) 3xy + 2y + 15z - 20 = 0
(c) 2xy + 4yz = 8
(d) 2x + 3y 4z = 6.© BrainMass Inc. brainmass.com December 24, 2021, 9:23 pm ad1c9bdddf

An equation is called linear if it is of the form:
where a, b and c are constants.
So, (a) is a linear equation, while (b), (c) are NOT.
Note: For (d): 2x + 3y â?" 4z = 6, as I am not sure what â?" stands for, it looks like some symbol, so if it is NOT "-" or "+", then it must be a nonlinear equation.© BrainMass Inc. brainmass.com December 24, 2021, 9:23 pm ad1c9bdddf>
