Hi, would it be possible for a bit of guidance on the following question?
I need to find the value of x, here is what I have done so far,
x/3 +15 = 3 (x-11)
Mulitpiled each side by 3 (the denominator)
3(x/3 + 15) = 9 (x-11)
Multilpied out the brackets
x + 45 = 9x-99
Subtract x ?
45 = 8x-99
Now I get a little stuck, I am pretty sure x =18 but cannot get this with the final steps of the calculation.
Any help would be very much appreciated.
You were doing fine. Now add 99 to both sides.
8x = 144
Then divide both sides by 8
x = 18
Brilliant, thanks for that
To solve for x in the equation 45 = 8x - 99, we can begin by isolating the variable x.
First, add 99 to both sides of the equation:
45 + 99 = 8x - 99 + 99
This simplifies to:
144 = 8x
Next, divide both sides of the equation by 8 to solve for x:
144/8 = (8x)/8
The left side simplifies to:
18 = x
Therefore, the value of x in the given equation is 18.
It seems that you made a mistake during the simplification process. When you subtract x from both sides of the equation 45 = 8x - 99, the equation should become 45 + x = 8x - 99, not 45 = 8x - 99 as you wrote.
To correct this, subtract 8x from both sides of the equation instead of x.
