Is x = 2 a solution to the following equation?

 -7x-16=-2 

No, the solution is x = -2

200

If  -3x+10=25 , what is the value of 

-3x+1?

The value of 

-3x+1 is 16

300

Can you find the mistake?

2x - 3(x-2)=15

2x - 3x + 6 = 15

5x = 15

x = 3

Combined 2x, -3x, and 6. They're not all like terms, only 2x and -3x can be combined!
