✔ 最佳答案
First step in this kind of equation is to rewrite xs on one side and the rest on the other side. so:2x+6x = 25 - 9 (remember that when you move one number from one side to the other you have to change sign!!)
than you add:
8x = 16
finally you divide 16 by the number next to the x, so that you have
x = 16/8 -- hence x = 2
You can do all these equations this way.

2x + 6x+ 9 = 25....subtract 9 from each side and add the x terms
8x = 16
x = 2
8x = 16
x = 2

Combine the variables.
8x + 9 = 25
Get the variable to be alone (subtract 9 from 25)
8x = 16
Now divide
16/8= 2
X = 2
hope this helps

2x + 6x + 9 = 25. Add the x terms together to get:
8x + 9 = 25. Subtract 9 from both sides of the equation.
8x = 25 - 9 = 16. Divide both sides by 8.
x = 2. Answer
8x + 9 = 25. Subtract 9 from both sides of the equation.
8x = 25 - 9 = 16. Divide both sides by 8.
x = 2. Answer
