Question

7/3x =21
Solve for x
Simplify your answer as much as possible

Answer 1

To solve the equation \(\frac{7}{3} x = 21\), you can follow these steps:

1. Start by isolating \(x\). To do this, multiply both sides of the equation by the reciprocal of \(\frac{7}{3}\), which is \(\frac{3}{7}\):

\[
x = 21 \cdot \frac{3}{7}
\]

2. Next, simplify the right side:

\[
x = \frac{21 \cdot 3}{7}
\]

3. Calculate \(21 \div 7\):

\[
x = 3 \cdot 3
\]

4. Now multiply:

\[
x = 9
\]

So, the solution is \(x = 9\).
