The image you provided contains a set of equations to solve, listed under different parts (a) through (f). Here's a breakdown of each:

• a) $7 - (64 + 6x) + 12 = 0$
• b) $3x - (17 - (6x + 3))) + 12x = -x + 1.3$
• c) $5 - (4.5x - 4.7) + 4.3 = 9$
• d) $3.8x - (64 + 6x) + 12 = 0$
• e) $-6.1(15 - 3x) + 12x = -x + 1.3$
• f) $5x - (4.5x - 4.7) + 4.3 = 9$

Would you like me to solve these equations for you step by step? Or if you have a specific question about one, feel free to ask!
