Answer:
Step-by-step explanation:
Solve for x each equation to find the the solution positive or negative.
1) 2x = 6
∴ x = 6/2 = 3 ⇒ positive solution
2) -2x = 6.1
∴ x = 6.1/(-2) = -3.05 ⇒ negative solution
3) 2.9* x= -6.04
∴ x = -6.04/2.9 = -2.08 ⇒ negative solution
4) -2.473 * x=- 6.859
∴ x = ( - 6.859)/( -2.473) = 2.77 ⇒ positive solution

Notes: the rules of positive and negative signs:
[tex]\frac{+}{+} =+\\\frac{+}{-} =-\\\frac{-}{+} =-\\\frac{-}{-} =+[/tex]
The same rules are correct if replaced the division by the multiplication.
