X = -3
Solution:
Distribute
6(x)+(6)(-1)+-x=-21
Combine
(6x+-x) + (-6) = -21
5x + -6 = -21
5x - 6 = -21
Add 6 to both sides
5x -6 + 6 = -21 +6
5x = -15
Divide both sides by 5
5x/5 = -15/5
x = -3
Answer:
The answer to your question is the last choice
Step-by-step explanation:
K = 5/9 (F + 459.67)
- Multiply by 9 both sides and simplify
9K = 5(9)/9 (f + 459.67)
9K = 5(f + 459.67)
- Divide by 5 both sides and simplify
9/5K = 5/5(F + 459.67)
9/5 K = F + 459.67
- Substract both sides by 459.67 and simplify
9/5K - 459.67 = F + 459.67 - 459.67
9/5K - 459.67 = F
It should be true but I’m not 100% sure
