If (3x2 + 22x + 7) ÷(x + 7) = 3x + 1, then (x + 7)(.

x+7=3x+1÷13+22x

x+7=3x+1÷13+22x

x+7=3x+1÷13+22x

If (3x2+22x+7)/(x+7)=3x+1 ,then (x+7)=(3x2+22x+7)/(3x+1)

Explanation:

This is because if the first expression was 8 then the 2nd 2 if we divide 8 by 2 we get 4 and to get the 1st number of the equation we have to multiply the answer and the 2nd number of the equation. However if we needed to find the 2nd number, we would do the opposite and divide the 1st number with the answer. This applies to every division equation.

Another example is 7/4=1.75 Lets put what we explained above into action.

7/4=1.75

1.75x4=7

7/1.75=4
