Question

Variables on both sides. Solve the equation.
7-n=n-4-1

Answer 1

move variables to the same side to make them easy to work with

Answer 2

First, move the \(-4\) and the \(-1\) onto the LHS

Before: \(7-n=n-4-1\)
Now: \(7+4+1-n=n\)

Simplify:

\(12-n=n\)

Move the \(n\) to the RHS
\(12=n+n\)

Simplify
\(12=2n\)

Solve:
\(n=\frac{12}{2}\)
\(n=6\)

Answer 3

-n-n=-4-1-7

Answer 4

Do you understand, @Jamiehughes?
