Answer 1

It looks like you're trying to solve an equation involving fractions or possibly performing operations with them. Let's clarify the equation you've provided.

If we interpret it as:

\[
-\frac{7}{1} + \frac{2}{1} b = \frac{7}{1}
\]

We can simplify this equation step by step.

1. Since \(\frac{7}{1} = 7\), we rewrite the equation as:

\[
-7 + 2b = 7
\]

2. Next, add \(7\) to both sides of the equation:

\[
2b = 7 + 7
\]

\[
2b = 14
\]

3. Now, divide both sides by \(2\):

\[
b = \frac{14}{2}
\]

\[
b = 7
\]

So, the solution is:

\[
b = 7
\]
