Isolate x; you must get all the constants on one side of the equation and the variables on the other side. Use subtraction/addition to do this. Reply to me once you've done that if you still need help.
First you have to change y to x
X= 2y+5/2
Then find y
(X-5/2)/2=y
So (X-5/2)/2 is the. Inverse function
4x - 2y = 14
y = 1/2x - 1
4x - 2(1/2x - 1) = 14
4x - x +2 = 14
3x + 2 - 2 = 14 - 2
3x = 12
3x / 3 = 12/3
x = 4
2x = y -10
2x + 7 = 2y
y - 10 + 7 = 2y
y -y -10 + 7 = 2y - y
-3 = y
8x - 1/3 y = 0
12x + 3 = y
8x - 1/3y = 0
8x -1/3( 12x + 3) = 0
8x - 4x - 3 = 0
4x -3 + 3 = 0 + 3
4x / 4 = 3/4
x = 3/4
To find the common difference between the numbers, let us first find the difference between the second number and the first number.
(5/16) - (1/4) = (5 - 4)/16
= 1/16
Let us now find the difference between the third number and the second number
(3/8) - (5/16) = (6 - 5)/16
= 1/16
From the above two deductions, we can conclude that the common difference is 1/16 and the correct option among all the options given in the question is the first option.
