Describe why you can change a subtraction problem into an addition problem
Elena-2011 [213]
A subtraction problem can be turned in to an addition problem because of negative numbers. Take 5-2=3 for example. If you change 5-2 into an addition problem then you would but he addition sign and a negative sign on 2. This will then leave you with the problem looking like 5+ -2. If you add 5 and -2 you will still get three.

Does anyone know what -23= 13w+2w+22 is plz help!
AlladinOne [14]

Answer:

w = -3

Step-by-step explanation:

-23 = 13w + 2w + 22

Combine like terms (add 13w and 2w and subtract 22 from both sides)

-45 = 15w

Divide both sides by 15

w = -3
