3/5x + 5 = 4/5
3/5x + 5 (-5) = 4/5 (-5)
3/5x = -4 1/5
3/5x/(5/3) = -4 1/5(/)(5/3)
x = (- 21/5)/ (5/3)
x = -21/5 x (3/5) (flip the signs by flipping the second fraction and the divide to a multiply)
x = -21/5 x 3/5
x = -63/25 or x = - 2.52

Answer:
5.35
Step-by-step explanation:
48.012001 is the answer to this problem
***(2x²+6x-8):(x+5)=2x-4
-2x²-10x
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
-4x-8
4x+20
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
12 ⇒ A. statement is true.
***When x=-5⇒2*(-5)²+6*(-5)-8=12⇒B. statement is true.
***2x²+6x-8 can also be written as (x+5)*(2x-4)+12 so (x+5) is a factor of 2x²+6x-8⇒C. statement is true.
***When x=5⇒2*5²+6*5-8=72 is not 12⇒D. statement is not true
***(2x²+6x-8):(x+5)=2x+16
-2x²+10x
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
16x-8
-16x+80
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
72⇒F. statement is not true
***E. statement is not true.
