5r + 8<63

Answer 1

Start by subtracting 8 from both sides :)
\[\huge~\rm~5r + 8-8<63-8\]

Answer 2

What are you left with?

Answer 3

5r<55
i think

Answer 4

Good now just divide both sides by 5r to isolate r :)
\[\huge~\rm~5r/5<55/5\]

Answer 5

so i think it would be 11 right

Answer 6

r=11

Answer 7

Thats almost correct!
We don't use the equal sign we use this <
so r<11

Answer 8
