What is the answer to -7d-22=4d?

1 answer:

4 0

First add 7d to both sides:
-22 = 11d
Now divide by 11 both sides
-2 = d

You can work on either side of the equation, I used the right side for the variables because it was easier to add to positive numbers than dealing with negative numbers on the left side:
-7d -4d = 22
-11d =22
d = -2

either way you get the same answer :)

No steps are wrong. To solve this equation, you need to isolate the y. So, you would add 4.6 to both sides to cancel out the 4.6 on the right side and isolate the y.

Misty purchased a pair of jeans that were originally $24, but were on sale for 1/3 off the total price. How much did she save?

uranmaximum [27]

So whenever a problem says "of" a value, multiply.
24 * 1/3 = 24/3 = 8

She saved 8 dollars.

Hope this helps! If you have any questions, just ask!
