Answer:
D. x= 10/3
Step-by-step explanation:
|x+3| = 4x -7
1. x+3 > 0 or x> -3
- x+3 = 4x - 7
- 4x -x = 3+7
- 3x = 10
- x= 10/3
Since 10/3 is greater than -3, it is accepted correct
2. x+3 < 0 or x < -3
- -(x+3) = 4x-7
- 4x+x = 7 -3
- 5x = 4
- x = 4/5
Here we have 4/5 > - 3, it is contradicting with x< -3 so this is not correct
So there is one solution:
