3.) 2 - \\frac{3}{4}(8x - 6) = 11

Explanation:

Step1: Distribute the fraction

$2-\frac{3}{4}\times8x+\frac{3}{4}\times6 = 11$ $2 - 6x+\frac{18}{4}=11$ $2 - 6x + 4.5=11$ $6.5-6x = 11$

Step2: Isolate the term with x

$-6x=11 - 6.5$ $-6x = 4.5$

Step3: Solve for x

$x=\frac{4.5}{-6}$ $x = - 0.75$

Answer:

$x=-0.75$
