Answer:


\frac18x-22

Step-by-step explanation:

Given expression:


(\frac78x-4)-3(\frac14x+6)

Expand:


\implies \frac78x-4-\frac34x-18

Gather like terms:


\implies \frac78x-\frac34x-4-18

Change 3/4 into eighths:


\implies \frac78x-\frac68x-4-18

Combine like terms:


\implies \frac18x-22

Answer:


\sf (x)/(8)-22

Step-by-step explanation:


\rightarrow \sf \left((7)/(8)x-4\right)-3\left((1)/(4)x+6\right)

remove parenthesis


\sf \rightarrow (7)/(8)x-4-(3x)/(4)-18

expand


\rightarrow \sf (7x)/(8)-(3x)/(4)-22

simplify


\rightarrow \sf (x)/(8)-22
