Answer:

x=3

Step-by-step explanation:

10x - 15 = 15

10x = 15 + 15

10x = 30 (divide both sides by 10 to get x)

10x/10 = 30/10

x = 3

10x + 15 =?
Solution:
-Group like terms on one side of the equal sign and once they cross the equal sign,the polarity changes
10x= - 15
- divide both sides by the number that x is carrying
10x/10 = -15/10
X= - 1.5
