Hi,
To answer your question, let me show you the solution
The given is (x-1)/2=8
The first thing you should do is cross multiply : (x-1)1 = 2 x 8
This should give you : X - 1 = 16
Since you have a negative one in the left side, transpose it to the right side or add 1 to both side, so : X - 1 + 1 = 16 + 1
This gives you : X = 17
Substitute the value of X to check : (17 - 1 ) / 2 = 8
Solve : 16 / 2 = 8 ; 8 = 8 (correct)
The value of X is 17 ; X = 17

well it is
(x-1)/2=8
=> x-1=2*8
=> x=16+1
=> x=17
therefore x=17 is the solution

(x-1)/2 = 8
cross multiplying
x-1 = 8*2
x-1= 16
shifting -1 to the other side( its sign changes when you shift it)
x= 16+1
x= 17.

In extensive-unfold variety, you're making y=0, then artwork the situation into this format: ax^2+bx+c=0 So, set up for (x + a million) squared, it incredibly is comprehensive with flow multiplication: (x + a million) * (x + a million) = (x^2 + 1x + 1x + a million) = (x^2 + 2x +a million) which eliminates the exponent 2. 2 * (x^2 + 2x + a million) = 2x^2 + 4x + 2 eliminates the ( ) & the ingredient 2 (a ingredient is a multiplier). 2x^2 + 4x + 2 - 8 = 2x^2 + 4x - 6 eliminates the -8 so, 2x^2 + 4x - 6 = 0 is it incredibly is extensive-unfold variety. factored variety skill they choose it to look like this: (ax + c) * (bx + d) = 0 (I often try this by guessing, and finding out till I discern it out, yet i think of there's a formulation for doing this) so, 2x^2 + 4x - 6 = 0 factored is: (2x + 6) * (x - a million) = 0 it works out to 2x^2 - 2x + 6x - 6= 0 simplified, it = 2x^2 + 4x - 6 = 0 chuffed Now?

(x-1)/2=8
multiply by 2
x-1=16
add 1 to both sides
x=17

(x - 1) / 2 = 8
1/2x - 1/2 = 8
1/2x = 8 + 1/2
1/2x = 8 1/2
x = (8 1/2) / (1/2)
x = 17/2 * 2
x = 17
Proof:
(17 - 1) / 2 = 8
16 / 2 = 8
8 = 8

Multiply both sides by 2
x - 1 = 16
x = 17
