Answer:
The value of f is 4π.
Step-by-step explanation:
The given equation is
[tex]f+3\pi=7\pi[/tex]
We need to find the value of f for the above equation.
Isolate f to solve the given equation.
Subtract 3π from both sides of the above equation.
[tex]f+3\pi-3\pi=7\pi-3\pi[/tex]
On combining like terms we get
[tex]f+(3\pi-3\pi)=(7\pi-3\pi)[/tex]
[tex]f=4\pi[/tex]
The value of f is 4π.
Substitute f=4π in the given equation to check the solution.
[tex]4\pi+3\pi=7\pi[/tex]
[tex]7\pi=7\pi[/tex]
[tex]LHS=RHS[/tex]
Therefore the solution is correct.
