Question

Solve for bb.
5, equals, 3, minus, one tenth, b
5=
3−
10
1
​
b

Answer 1

To solve for \( b \) in the equation

\[
5 = 3 - \frac{1}{10}b,
\]

follow these steps:

1. **Isolate the term with \( b \)**:

Start by subtracting 3 from both sides:

\[
5 - 3 = -\frac{1}{10}b,
\]

which simplifies to

\[
2 = -\frac{1}{10}b.
\]

2. **Eliminate the negative fraction**:

To eliminate the negative sign, multiply both sides by -1:

\[
-2 = \frac{1}{10}b.
\]

3. **Get rid of the fraction**:

Multiply both sides by 10 to solve for \( b \):

\[
-2 \times 10 = b,
\]

which gives us

\[
b = -20.
\]

Thus, the solution for \( b \) is

\[
\boxed{-20}.
\]
