Answer 2

Let's solve the inequality and equation separately.

Solving the inequality: 1 < 15 - 7x < 2 Subtracting 15 from all parts of the inequality gives: -14 < -7x < -13 Dividing by -7 (and reversing the inequality signs because we're dividing by a negative number) gives: 2 > x > 13/7

So the solution to the inequality is x is greater than 13/7 but less than 2.

Solving the equation: 3x - 3 = 0 Adding 3 to both sides gives: 3x = 3 Dividing by 3 gives: x = 1

So the solution to the equation is x = 1.

Therefore, the solution to the system of inequality and equation is that x is greater than 13/7 but less than 2, and also x = 1.
