Question

$$\cdot\frac{x}{10}+3=9$$

Answer

x=3/5

Solution


Simplify  \(x\times 10\)  to  \(10x\).
\[10x+3=9\]
Subtract \(3\) from both sides.
\[10x=9-3\]
Simplify  \(9-3\)  to  \(6\).
\[10x=6\]
Divide both sides by \(10\).
\[x=\frac{6}{10}\]
Simplify  \(\frac{6}{10}\)  to  \(\frac{3}{5}\).
\[x=\frac{3}{5}\]
