If to simplify:
= 6 1/5 - 1/4x(7 2/3)
= 6 1/5 - 1/4x(23/3)
= 6 1/5 - 23/12x
= 6 1/5 - 1 11/12x
Answer: 6 1/5 - 1 11/12x
If finding value of x:
6 1/5 - 1/4x(7 2/3) = 0
31/5 - 1/4x(23/3) = 0
23/12x = 31/5
x = 372/115 or 3 27/115
Answer: x = 372/115 or 3 27/115
Checking:
6 1/5 - 1/4(372/115[7 2/3]) = 0
31/5 - 93/115(23/3) = 0
31/5 - 2,139/345 = 0
31/5 - 31/5 = 0
0 = 0
