Answer:
x + 5 = -3
x=-10
- -2x -4 +8x -12
2(3x - 8)
Step-by-step explanation:
1-
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
2-
Collect like terms: 6x-4-12
Factor out 2 from the expression : 2(3x - 8)
