3x + 7 - 6 = (8)/(7) - 0 \\ \\ 3x + 1 = (8)/(7) \\ \\ 3x = (8)/(7) - 1 \\ \\ 3x = ( 8 - 7)/(7) \\ \\ 3x = (1)/(7) \\ \\ x = (1)/(7 * 3) \\ \\ x = (1)/(21) .

Answer:


\boxed{\sf x = (1)/(21)}

Step-by-step explanation:


\rightarrow \sf 3x+7-6= (8)/(7) - 0

simplify the following


\rightarrow \sf 3x+1= (8)/(7)

subtract 1 from both sides


\rightarrow \sf 3x+ 1 -1= (8)/(7) - 1

simplify the following


\rightarrow \sf 3x= (1)/(7)

multiply both sides by 1/3


\rightarrow \sf 3x \cdot (1)/(3)= (1)/(7)\cdot (1)/(3)

simplify the following


\rightarrow \sf x = (1)/(21)
