Example

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

Question

$$3-2x=3(2-x)$$

Answer

x=3

Solution


Expand.
\[3-2x=6-3x\]
Subtract \(3\) from both sides.
\[-2x=6-3x-3\]
Simplify  \(6-3x-3\)  to  \(-3x+3\).
\[-2x=-3x+3\]
Add \(3x\) to both sides.
\[-2x+3x=3\]
Simplify  \(-2x+3x\)  to  \(x\).
\[x=3\]
