Example

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

Question

$$\left. \begin{array} { l } { \frac { x - 5 } { 3 } - \frac { x - 3 } { 4 } } \\ { = \frac { x } { 2 } - 1 } \end{array} \right.$$

Answer

x=(-3*h+1)/2

Solution


Regroup terms.
\[-3h=2x-1\]
Add \(1\) to both sides.
\[-3h+1=2x\]
Divide both sides by \(2\).
\[\frac{-3h+1}{2}=x\]
Switch sides.
\[x=\frac{-3h+1}{2}\]
