Answer:
x=-[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
subtract -3(2x-1)+8=15
-8 -8
_____________
-3(2x-1)=7
divide
[tex]\frac{-3(2x-1)}{-3} =\frac{7}{3}[/tex]
then simplify
2x-1=[tex]\frac{7}{3}[/tex]
add both sides
2x-1+1=[tex]\frac{7}{3}[/tex]+1
simplify again
2x-1+1=[tex]\frac{7}{3}[/tex]+1=2x=[tex]-\frac{4}{3}[/tex]
divide by 2
2x=[tex]-\frac{4}{3}[/tex]
-2 -2
_________
2x÷2=1
[tex]-\frac{4}{6}divided by 2[/tex]
x=-[tex]\frac{2}{3}[/tex]
