Answer:
Error: +3x should be -3x
x should equal 3
Step-by-step explanation:
In this problem, you have to pay attention how values are transferred from one side to the other. This includes paying attention t the signs.
In 3x + 4 = 8x - 11, you want to try an keep all the values positive
3x + 4 = 8x - 11
- 3x - 3x
4 = 5x - 11
+11 +11 <--This part of the equation was correct.
15 = 5x
/5 /5 <--This part of the equation should result in dividing by 5
3 = x
Hope this helps!
