1. simplify 1/3 ( c + 1 ) to c + 1/3 ( c + 1 over 3 = 1/6 (3c - 5)
2. simplify 1/6 (3c - 5) to 3c - 5 over 6 ( c + 1 over 3 = 3c - 5 over 6 )
3. multiply both sides by 6 [The LCM of 3, 6] 2(c + 1) = 3c - 5
4. expand (2c + 2 = 3c - 5)
5. subtract 2c from both sides (2 = 3c - 5 - 2c)
6. simplify 3c - 5 - 2c to c - 5 (2 = c - 5)
7. add 5 to both sides (2 + 5 = c)
8. simplify 2 + 5 to 7 (7 = c)
9. switch sides (c = 7 )
so in conclusion the answer is 7.
Answer:
8 gallons
Step-by-step explanation:
Total gas in the car = 14 gallons
Each hour gas usage = 1.5 gallons
Total hours traveled = 4 hours
Left gas after 4 hours
= 14-1.5(4)
=14-6
=8 gallons
Left gas after t hours
=14-1.5t
Hence the answer is after 4 hours, 8 gallons are left after t hour(s) 14-1.5t

Answer:
x = −4
Step-by-step explanation:
Add x to both sides of the equation. x + 4 + x = − 4 Add x and x . 2 x + 4 = −4
Subtract 4 from both sides of the equation. 2 x = −4 − 4 Subtract 4 from - 4. 2x = −8
Divide each term in 2x = −8 by 2. 2x/2 = −8/2
Cancel the common factor. 2x/ 2 = −8/2 Divide x by 1. x = −8/2
Divide −8 by 2. x = −4
