Answer:
r=8
Step-by-step explanation:
56=7r
first I simplified the equation to the form, which is simple to understand
56=7r
Then I move all terms containing r to the left and all other terms to the right.
-7r=-56
Next I simplified the left and right the side of the equation.
-7r=-56
Then i divided both sides of the equation by -07 to get r.
r=8
