Question

Find the sum of 5x+20 and the opposite of 20. Write an equivalent expression in standard form. Justify each step.

Answer 1

Do 5x + 1 instead of 5x + 20, because there was more than likely a mistype.

Now we are also looking for the reciprocal so we do (5x + 1)/20

Either that is the answer or there is something missing. If this is not the answer then there needs to be a number we can set the equation equal to

Answer 2

The answer would more than likely to be 4..
because u divide 5 on both sides and it will give you x=4
