Answer:
v=11/5 or v=2.2
Step-by-step explanation:
The wording of this question is a little confusing but if it says what I think it does (5/3v+4=8-1/3) then this is the answer.
One step equation, where only one step is required to solve the problem. Example:
20 = 5x
4 = x
Fractions:
1/2 + x = 3/2
x = 3/2 - 1/2
x = 1
Decimals:
0.5 + x = 1.5
x = 1.5 - 0.5
x = 1
Real world problem: (word problem and equation)
It costs $5 per hour to rent a canoe plus a $3 rental fee. How much will the total be if you plan on renting the canoe for 3 hours?
y = 5x + 3
y = total cost ; x = number of hours rented
y = 5×3 + 3
y = 15 + 3
y = $18
