Answer 1

To solve the equation -22 = -40r, isolate r by adding 22 to both sides and then dividing both sides by -40. The solution is r = 11/20. The solution is correct when checked.

Step-by-step explanation:

To solve the equation -22 = -40r, we need to isolate r. We can do this by getting rid of the constant term on the right side. We can start by adding 22 to both sides of the equation:

-22 + 22 = -40r + 22

0 = -40r + 22

Next, we can subtract 22 from both sides:

-22 = -40r

Finally, we can divide both sides by -40 to isolate r:

r = -22 / -40

By simplifying the fraction, we get:

r = 11/20

Now, let's check our solution by substituting r = 11/20 into the equation:

-22 = -40(11/20)

-22 = -22

The equation is true, so the solution is correct.
