Answer:
x = 3, the error is that the -2x should be added.
Step-by-step explanation:
The -2x should be added to the left side.

3x + 2x = 8 + 7
5x = 15
x =3

We have:
ba + 3ca = -2
Extract common factor "a":
a(b + 3c) = -2
Divide by the term (b + 3c):
This is equal to...
We want "x" so we need to isolate it using laws of exponents...
because 
![x=\sqrt[3]{8^{2}}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B8%5E%7B2%7D%7D)
because ![x^{a/b}=\sqrt[b]{x^{a}}](https://tex.z-dn.net/?f=x%5E%7Ba%2Fb%7D%3D%5Csqrt%5Bb%5D%7Bx%5E%7Ba%7D%7D)
x = 4
