Example

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

Question

$$B=(-3,3),(-2,2),(-1,1),(0,0),(1,1),(2,2),(3,3)$$

Answer

B=-3,3,-2,2,-1,1,0

Solution


Remove parentheses.
\[B=-3,3,-2,2,-1,1,0,0,1,1,2,2,3,3\]
Already solved. No work needed.
\[B=-3,3,-2,2,-1,1,0,0,1,1,2,2,3,3\]
Therefore,
\(B=0,\pm 3,\pm 2,\pm 1\)
