To solve this equation for x, we need to isolate x on one side of the equation. First, we'll combine the like terms on each side of the equation:
7 - 2x = 3x - 3
Next, we'll add 2x to both sides of the equation:
7 = 5x - 3
Then, we'll add 3 to both sides of the equation:
10 = 5x
Finally, we'll divide both sides of the equation by 5:
2 = x
Now that we know x = 2, we can find 6x by multiplying x by 6:
6x = 6(2) = 12
Therefore, 6x is equal to 12.
Answer: E
7 - 2x = 3x - 3

7 – 2x = 3x – 3
Combine like terms, move -2x to the RHS of the equation and -3 to the LHS of the equation, this changes the signs to the opposite signs.
7 + 3 = 3x + 2x
10 = 5x
x = 2
6x = 12
Answer = E
