16320.
Reducing (canceling) the factor 80*17*3 = 4080 in the numerator and denominator, you get the fraction
equal to 7 which is the simplest form.

Step-by-step explanation:
Answer:
1/5
Step-by-step explanation:
In order to solve this, you need to simplify. In this case, we would need to distribute first.
-5x - (-7 - 4x) = -2(3x - 4)
-5x + 7 + 4x = -6x + 8
Combine like terms:
-5x + 7 + 4x = -6x + 8
-5x + 6x + 4x = 8 - 7
-x + 6x = 1
5x = 1
X needs to be by itself, so you would divide by 5 (the coefficient in front x) on both sides. So,
5x = 1
x = 1/5
