Answer:
x = -9/2
Step-by-step explanation:
1. Divide 9 by -1/3:
÷ = ·
= -27
2. Divide both sides by 2:
2(x - 9) = -27
(x - 9) =
3. Add 9 to both sides:
x =
(or 4.5 if you need it in decimal form)

Answer:
- The correct equation is 6s = 7.80
- The solution of the equation is s = $1.30
Step-by-step explanation:
To find the product of 6 and a number, first we denote the unknown number as s.
The product of 6 and s is the same as 6s.
If the product of both numbers is $7.80, then 6s = $7.80
The correct equation is therefore 6s = $7.80
To get the value of s, we will divide both sides by 6 to have:
6s/6 = $7.80/6
s = $1.30
Based on the calculation, the following statements are true
- The correct equation is 6s = 7.80
- The solution of the equation is s = $1.30
