Answer:
x = -15
Step-by-step explanation:
Step 1: Write equation
3(2x - 5) - 3(x - 7) = 2x - 9
Step 2: Distribute
6x - 15 - 3x + 21 = 2x - 9
Step 3: Combine like terms
3x + 6 = 2x - 9
Step 4: Subtract 2x on both sides
x + 6 = -9
Step 5: Subtract 6 on both sides
x = -15

Answer:
A is a function; B, C and D are not.
Step-by-step explanation:
In other words: Identify the sole function among these relationships.
A function maps any input onto exactly one output.
If a relationship maps any input onto more than one output, it is not a function.
Thus, we eliminate B, C and D. In B, for example, we have the inputs {1, 2, 3}, where the '1' has two y-values associated with it.
On the other hand, A has the domain {-1, 0, 1, 2}, and all four inputs have exactly one associated output.
