Question

Evaluate x^2-x for the value of x satisfying 6 (x - 3) + 3 = 6x - 3 (3 - x)

Answer 1

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
