11 = 12 - q
solve & explain solution

q=-1

Step-by-step explanation:

subtract 12 from each side 11-12=-1

therefore, -1=q

1

Step-by-step explanation:

1.  (you would need to subtract 12 on both sides so that 'q' would be isolated)

  11  =  12 - q

 - 12       -12

2.  (then you would you need to divided both sides by -1)

  -1  = -q

  ÷ 1    ÷1

3. (final answer)

  1  =  q
