Example

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

Question

$$1.6km=1600km$$

Answer

k=0

Solution


Cancel \(m\) on both sides.
\[1.6k=1600k\]
Divide both sides by \(1.6\).
\[k=1000k\]
Subtract \(k\) from both sides.
\[0=1000k-k\]
Simplify  \(1000k-k\)  to  \(999k\).
\[0=999k\]
Divide both sides by \(999\).
\[0=k\]
Switch sides.
\[k=0\]
