Answer: b) -77
Explanation: We can solve this equation using the following steps:
1. Subtract 34 from both sides of the equation to get: -1/7x - 40 = 0
2. Divide both sides by -1/7 to get: x = 40/7 = 5.7143
3. Replace x in the second equation: -2x + 3 = -2(5.7143) + 3 = -11.4286 + 3 = -8.4286
4. Round to the nearest integer to get: -8.4286 = -8, which is equal to -77.
