3(4u-6)=2(4u-3)-(u-8)
what is u
12u-18=8u-6-u+8
Can you take it from here?
so I would have combine like terms then add right?
what about 3(n-2)-2(3-n)=4(n-3)
same thing...use distributive property to multiply, do the operations, solve for n
give it a try...
u could be "any" number. Since you don't know its value, just multiply by it, like this...(remember the distributive property). First one side of equal, then the other...
3x4u - 3x6 = (2x4u - 2x3) -u +8 (last part is because -x+ is - and -x- is +...but you know that, right) Now do the math
3x4u= 12u (see how it works?) Now try...
i still don't understand how to find the value of u
you would have to do the math operations for each side of the equation.
12u - 18 = 8u -6 -u +8
Now put the similar terms together on one side and solve for u, like this
12u - 8u +u = 18 +8 -6 Now try and went you get to the part where a number multiplies U = a number, divide the number by coefficient of U...follow me?
3/4(12u-8) in distributive property

To find the value of "u" in the equation 12u - 18 = 8u - 6 - u + 8, let's simplify it step by step.
First, combine like terms on each side of the equation. On the left side, we have 12u, and on the right side, we have 8u - u = 7u. And on the right side, we have -18 - 6 + 8 = -16.
Now, our equation becomes:
12u - 16 = 7u
To isolate the variable "u" on one side, we need to get rid of the 7u term on the right side. We can do this by subtracting 7u from both sides:
12u - 7u - 16 = 7u - 7u
This simplifies to:
5u - 16 = 0
Next, we want to move the constant term (-16) to the other side, so we add 16 to both sides:
5u - 16 + 16 = 0 + 16
This gives us:
5u = 16
Finally, to solve for "u," we divide both sides of the equation by the coefficient of "u," which is 5:
(5u)/5 = 16/5
The "5" cancels out on the left side, leaving us with:
u = 16/5
So, the value of "u" is 16/5 or 3.2.
