Answer:

Explanation:

5 times -4 is -20, so the equation becomes -20 - r + 1 = -37

-20 plus 1 equals -19, so the equation is now -19 - r = -37

Then you add 19 to both sides to isolate r

-r = -18

To get a positive r, divide or multiply both sides by -1, and you get r = 18

5(-4)-r+1=-37

Simplify:


-20-r+1=-37

Combine Like Terms:


(-r)+(-20+1)=-37


-r-19=-37

Add 19 to both sides:


-r-19+19=-37+19


-r=-18

Divide both sides by -1:(To remove the negative from the variable r)


(-r)/(-1)=(-18)/(-1)


\boxed{r=18}
