In this problem, we have the following equation of a line written in Standard form:

So we need to choose the equations that has the same solutions as this equation. If we multiply each equation by a constant term and find the same solution as the given equation, then they will have the same solution. This is only true fro options B, C, E and F.
Option B.

So we get the same given equation. This option is valid!
Option D.

So we get the same given equation. This option is valid!
Option E.

So we get the same given equation. This option is valid!
Option F.

So we get the same given equation. This option is valid!
For the other options, there is no any constant term that multiplies both sides of the equation and gives us the same given equation.

Answer:
63
Step-by-step explanation:
Set up the proportion
(6x+3)/17 = (8x - 1)/21 Cross Multiply
21 * (6x + 3) = 17 (8x - 1) Remove the brackets
126x + 63 = 136x - 17 Subtract 126x from both sides
63 = 136x - 126x - 17 Combine
63 = 10x - 17 Add 17 to both sides
63 + 17 = 10x Combine the left
80 = 10 x Divide by 10
80/10 = x
x = 8
Now you want 8x - 1
8*8 - 1 = 63
