Help i dont know what im doing this is due today

Hunter-Best [27]

Answer:

$\frac{4}{5}$ x + 5 = -3

x=-10

-2x -4 +8x -12

2(3x - 8)

Step-by-step explanation:

Multiply both sides of the equation by 5: 4x + 25 = -15

Move the constant to the right-hand side and change its sign : 4x = -15 - 25

Calculate the diffrerence: 4x = -40

Divide both sides of the equation by 4 : x= -10

Collect like terms: 6x-4-12

Factor out 2 from the expression : 2(3x - 8)
