Answer:

800 + 70 + 9 (See explanation!)

Step-by-step explanation:

Expanded form of a number is another way of writing out what it is. For example: 24 is 20 + 4. Another example: 111 is 100 + 10 + 1. Hopefully you see a pattern here. Now, looking at 879, we see that there is an 8 in the hundreds place, 7 in the tens place, and 9 in the ones place. Once again, we're just trying to represent the number through addition. So the answer is:

879

800 + 70 + 9

294/X= -14
Cross multiply
294= -14X
Divide both sides by -14
294 : -14 = -21
-14 gets cancelled out so the X is isolated
X= -21 or -21=X it doesn’t really matter which way you put it
