Answer:
-2/3
Explanation:
Plug in x given the expression is 1/3x - 3/4.
The value of x is 1/4.
1/3x - 3/4
1/3(1/4) - 3/4
1/12 - 3/4
Make 1/12 and -3/4 have a common denominator.
12 is the common denominator so make -3/4 have a denominator of 12.
-3/4(3/3)
-9/12
Now add them:
1/12 - 9/12
= -8/12 which simplifies to -2/3
