Answer 1

Solution to the System of Inequalities

To find the solution to the system of inequalities {4x - 5 > 7, x < 8a}, we need to determine which values of x satisfy both inequalities.

Let's analyze each inequality separately:

1. 4x - 5 > 7: To solve this inequality, we can add 5 to both sides of the equation: 4x - 5 + 5 > 7 + 5 4x > 12 Then, we divide both sides of the equation by 4: 4x/4 > 12/4 x > 3

2. x < 8a: This inequality does not provide enough information to determine the value of x. We need to know the value of 'a' to solve it.

Therefore, the solution to the system of inequalities {4x - 5 > 7, x < 8a} depends on the value of 'a'. Without knowing the value of 'a', we cannot determine which of the given options (3, 4, -3, or 9) is a solution to the system.

If you provide the value of 'a', I can help you find the specific solution.
