4(2x - 3) - 3(x - 4) + 7x = 6
or 8x - 12 - 3x + 12 + 7x = 6 [after moving the brackets]
or (8x + 7x) - 3x + (12 - 12) = 6
or 15x - 3x + 0 = 6 [after moving the brackets]
or 12x + 0 = 6
or 12x = 6 [removing 0]
You gave four options according to the required solution, the answer is number b. which is 12x = 6
