8(4u-1)-12u=11(2u-6)
32u-8-12u=22u-66
-12
20u-8=22u-66
-20u
-8=2u-66
-8
2u=74
u=37
i kno 1 messed up but idk where
-8=2u-66
+66
o ok thx
It looks like there may have been an error in your calculations. Let's go through the steps together to identify where the mistake might be.
Starting with the original equation:
8(4u-1) - 12u = 11(2u-6)
First, distribute the 8 and 11 to the terms within the parentheses:
32u - 8 - 12u = 22u - 66
Next, combine like terms on both sides of the equation:
(32u - 12u) - 8 = 22u - 66
20u - 8 = 22u - 66
Now, let's isolate the variable u by subtracting 22u from both sides:
20u - 8 - 22u = -66
Simplify the equation:
-2u - 8 = -66
To isolate the variable u, we need to get rid of the constant term (-8) on the left side. To do so, add 8 to both sides:
-2u - 8 + 8 = -66 + 8
-2u = -58
Finally, divide both sides of the equation by -2 to solve for u:
(-2u)/-2 = -58/-2
u = 29
Therefore, the value of u should be 29, not 37. It seems like the mistake may have occurred during the simplification of the equation -8 = 2u - 66. On this step, it should have been -74, not -8.
I hope this clarifies where the error occurred. If you have any further questions, feel free to ask!
