Answer:
x=-![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
Step-by-step explanation:
subtract -3(2x-1)+8=15
-8 -8
_____________
-3(2x-1)=7
divide
then simplify
2x-1=![\frac{7}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D)
add both sides
2x-1+1=
+1
simplify again
2x-1+1=
+1=2x=![-\frac{4}{3}](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B3%7D)
divide by 2
2x=![-\frac{4}{3}](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B3%7D)
-2 -2
_________
2x÷2=1
![-\frac{4}{6}divided by 2](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B6%7Ddivided%20by%202)
x=-![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
