Answer :

Sure, let's solve the equation step-by-step:

We start with the equation:
[tex]\[ -5r = 55 \][/tex]

We need to isolate the variable [tex]\( r \)[/tex]. To do this, we can divide both sides of the equation by -5.

Step-by-step, it looks like this:

1. Start with the equation:
[tex]\[ -5r = 55 \][/tex]

2. Divide both sides of the equation by -5 to solve for [tex]\( r \)[/tex]:
[tex]\[ r = \frac{55}{-5} \][/tex]

3. Perform the division:
[tex]\[ r = -11 \][/tex]

Therefore, the solution to the equation [tex]\( -5r = 55 \)[/tex] is:
[tex]\[ r = -11 \][/tex]
