Answer:
11/12
Step-by-step explanation:
to find the value of f , we need to move the -2/3 to the other side of the equal sign.
[tex]f - \frac{2}{3} = \frac{1}{4}[/tex]
Note : is you move a number from one side of the equal sign to the other, this changes the sign of the number ( eg , -2/3 becomes +2/3)
[tex]f = \frac{1}{4} + \frac{2}{3}[/tex]
f = [tex]\frac{11}{12}[/tex]
