Answer:
to setup the model linear equation to fit a real world application we must first determine the non quantities and the find the unknown quality as a variable can be begin to interview to the voice as mathematical expressions using mathematical symbols
Answer:
2
Step-by-step explanation:
We can first find x:
6 (x - 3) + 3 = 6x - 3 (3 - x)
6x - 18 + 3 = 6x - 9 + 3x
6x - 15 = 9x - 9
We can then islolate x, getting 3x = -6 and x = -2.
We can then plug in -2 for x and solve x^2 - x:
(-2)^2 - 2 = 4 - 2 = 2
