r = 23  hope this helped :)

Step-by-step explanation:

-14r-19=303

-14r=322

322/-14=23

R=-23

Step-by-step explanation:

The problem is -14r-19=303

To solve this we need to isolate the variable to get the value of R.

First, let's move the -19 on both sides.

To move this number we must add it to BOTH sides. (THE OPPOSITE)

The problem now becomes -14r=322.

Now to isolate we must get rid of the -14.

We can do this by doing the opposite of multiplication which is division.

322/-14=-23 (REMEMBER NEGATIVE x NEGATIVE = POSITIVE)

Our answer here is -23.

To check we can insert -23 inside the equation,

now it stands as

-14(-23)-19=303

322-19=303

303=303 (TRUE)
