Solve the linear equation.Please explain.Thanks
f/3 -3=1
A.-10 B.-12 C.10 D.12
Add 3 to both sides. f/3=4. What number divided by 3 equals 4?
Thanks Jen
To solve the linear equation (f/3) - 3 = 1, we want to isolate the variable f on one side of the equation. Here's how you can do it:
1. Start by getting rid of the constant term on the left side of the equation. In this case, subtract 3 from both sides:
(f/3) - 3 + 3 = 1 + 3
(f/3) = 4
2. To get rid of the fraction, we can multiply both sides of the equation by the denominator of the fraction, which is 3 in this case:
3 * (f/3) = 3 * 4
f = 12
Therefore, the solution to the equation (f/3) - 3 = 1 is f = 12.
So, the correct answer choice is D. 12.
