what is u
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?
