Answer: x = -29
Step-by-step explanation:
-0.59x+0.39x=5.8
Collect like terms
-0.2x = 5.8
Divide both sides of the equation by -0.2
x = -29
Response to user in comments:

Answer:
a). 5x - 12 b). 2x(4x + 3)
Step-by-step explanation:
a). 7(x - 2) - 2(x - 1)
= 7x - 14 - 2x + 2
= 5x - 12
b). 8x² + 6x
2x(4x + 3)
Answer: x=1
Step-by-step explanation:
4x-12x=-1-7
