3(4u6)=2(4u3)(u8)
what is u
12u18=8u6u+8
Can you take it from here?
so I would have combine like terms then add right?
what about 3(n2)2(3n)=4(n3)
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?
