Question

PLEASE HELP!!! will give brainlisest

Answer 1

Answer:

$\sf \dfrac{x}{8}-22$

Explanation:

$\rightarrow \sf \left(\dfrac{7}{8}x-4\right)-3\left(\dfrac{1}{4}x+6\right)$

remove parenthesis

$\sf \rightarrow \dfrac{7}{8}x-4-\dfrac{3x}{4}-18$

expand

$\rightarrow \sf \dfrac{7x}{8}-\dfrac{3x}{4}-22$

simplify

$\rightarrow \sf \dfrac{x}{8}-22$

Answer 2

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:

$\implies \frac18x-22$
