Lets space this out so it isnt so confusing
7x - (1/4) - 1/3(2x-1-x/2) = 10/3
Expand and collect terms
7x -(1/4) - 1/3 (3/2 x - 1)= 10/3
7x - (1/4) - x/2 + 1/3 = 10/3
13/2 x + 1/12 = 10/3
Express with same denominator
78/12 x + 1/12 = 40/12
78/12 x = 39/12
Multiply by 12 to get 78 x = 39 and x= 1/2

The answer is x=1/2.
To solve:
1) Breakdown the equation in the ( ). Multiply -1/3 to each of the factors in the ( ).
-1/3 * 2x = -2x/3
-1/3 * -1 = 1/3 (2 negative #s multiplied become a+)
-1/3 * -x/2 = x/6
The equation is now 7x - 1/4 - 2x/3 + 1/3 + x/6 = 10/3
2) Move the non X factors to the right side of the equation.
The equation is now 7x - 2x/3 + x/6 = 10/3 + 1/4 - 1/3
3) Using basic fraction addition, find the common denominator for the equation. The common denominator is 12. Multiply all of the factors by 12.
The equation is now 84x/12 - 8x/12 + 2x/12 = 40/12 + 3/12 - 4/12.
4) Add each side of the equation.
The equation is now 78x/12 = 39/12.
5) Multiply each side by 12 to remove the denominator.
The equation is now 78x = 39.
6) Solve for x by dividing both sides of the equation by 78.
The result is x = 39/78 or 1/2

First you need to simplify the equation to get rid of the fractions: Common denominator is 12 so multiply both sides of the equation by 12 and the result is:
84x -3-4(2x-1-x/2) = 40
Now get rid of the parentheses
84x-3-8x+4+2x = 40
Get the x's together on one side and the numbers together on the other side:
78x = 39
x= 1/2
To check place the value of x =1/2 back into the original equation and you should get 40=40.

Q 1. 7x - 1/4 - 1/3 ( 2x - 1 - x/2) = 10/ 3.
So we will first try to solve the bracket . i .e (2x - 1 -x/2) or (3x/2 - 1)
Now putting the values in the given expression we get,
7x - 1/4 - 1/3(3x/2 - 1) =10/3
or 7x - 1/4 - x/2 + 1/3 = 10/3
or 7x - x/2 = 10/3 + 1/4 - 1/3
or 13x/2 = 13/4
or x= 1/2

Mary wasn't coaching, she replaced into teaching the servants on the marriage by way of fact she replaced into there to help with the arrangements of the marriage banquet. yet sure, God's people ought to obey the training of Christ - the two in OT (in view that He quoted it this type of great style of circumstances) and NT.
