Question

What is the equation -5-r=1+2r

Answer 1

r=-2 because you can add the 5 to the one and that cancels out the -5 on the left, now your equation is -r=6+2r so you can subtract the 2r from both sides and that leaves you with -3r=6 all there is to do now is divide by -3 on both sides

Answer 2

`-5-r=1+2r`


`-r=1+2r+5`


`-r=2r+6`


`-r-2r=6`


`-3r=6`
`|\text{Isolate r}`


`r=-2`
