Question

Solve 3x - 7 > 5 or 2x + 6 < 12.

Answer 1

Again, solve both inequalities. For the first, you get that x > 4. For the second, you get that x < 3. Since a number cannot be both > 4 and < 3, there is no solution to this system of inequalities.

Answer 2

3x > 12
x > 4

2x < 6
x < 3
no solution

Answer 3

x>4 or x<6
