Plus 16 on both side and negative 12plus 16 is 4 so x equals 4
Looking at this triangle, we can see that is a form of a 45, 45, 90 triangle
This would mean that 2x-24=x-2
Solve: 2x-24=x-2
subtract x from both sides and add 24 to both sides...
x=22
Inequality : 19.50n+24≤$110

86/19.50 = 4.4
You can't have a fraction of a DVD, so you have to round down to 4.
