By inspection 4x3=12 and 2x9=18, therefore x=2 and y=1. Took about 1/5 of the time

It all depends on the intent, the long way displays more concepts

Clearly done, but no need to work out both scenarios. From (1) / (2) you got x - y = 1 Just plug it back into (1) 2^(1-y) x 3^y = 12 so 2^y x 3^y = 6 6^y = 6 => y = 1, so x = 2

Why divide by 2? Instead I multiplied it first by 2, then by 4 (so times 8 overall) thus avoiding fractions in my working until the last step.

Completing the square method requires that you make the coefficient of x squared be 1

Easily factored instead of completing the square: (2x - 3)(x + 3) = 0, so x = 3/2 & -3.

After x=2 at 0.48 by elimination, substitute for x into either equation and solve for y. No need for a second elimination process. 🇦🇺
@CalvinceOnlineMath5 ай бұрын
Thank you for the sentiments. This depends on what your professor was testing; if the instructions are ’use elimination method’ then don’t mix with substitution, just eliminate one variable to solve for the other in turns
