ArbitrLikvidat [17]2 years ago

Answer:

\boxed{\sf x = \dfrac{1}{21}}

Explanation:

\rightarrow \sf 3x+7-6= \dfrac{8}{7}  - 0

simplify the following

\rightarrow \sf 3x+1= \dfrac{8}{7}

subtract 1 from both sides

\rightarrow \sf 3x+ 1 -1= \dfrac{8}{7}   - 1

simplify the following

\rightarrow \sf 3x= \dfrac{1}{7}

multiply both sides by 1/3

\rightarrow \sf 3x \cdot \dfrac{1}{3}= \dfrac{1}{7}\cdot \dfrac{1}{3}

simplify the following

\rightarrow \sf x = \dfrac{1}{21}

3x + 7 - 6 =  \frac{8}{7}  - 0 \\  \\ 3x + 1 =  \frac{8}{7}  \\  \\ 3x =  \frac{8}{7}  - 1 \\  \\ 3x =  \frac{ 8 - 7}{7}  \\  \\ 3x =  \frac{1}{7}  \\  \\ x =  \frac{1}{7 \times 3}  \\  \\ x =  \frac{1}{21} .
