Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$\frac{ x }{ 9 } +7=10$$

Answer

x=27

Solution


Subtract \(7\) from both sides.
\[\frac{x}{9}=10-7\]
Simplify  \(10-7\)  to  \(3\).
\[\frac{x}{9}=3\]
Multiply both sides by \(9\).
\[x=3\times 9\]
Simplify  \(3\times 9\)  to  \(27\).
\[x=27\]
