Since 9z is a multiple of 3z, it is automatically the LCM.
x, y and z are the variables.
3 times X= 3XBecause it is the same as 1X plus 1X plus 1X.The X has an 'invisible' 1 in front of it....Another example could be, What is 4 times X + 2?It would equal 4X + 2, because when doing algebra you can only add things called 'like terms' so you can only add things like 2y+7y and 4yz+2yz or 4+3.But you cannot add terms that are different, such as 2y+3z or 5+7x, they will just stay the same. So, 2y+3z=2y+3z and 5+7x=5+7xHowever, you can MULTIPLY anything, so 2y times 3z= 6yz (2 times 3=6) and 5 times 7x= 35x and 4x times 3x= 12x2, this is because you have 2 xs!So overall this is what you should know from all the above:You can multiply un-like terms! Even if the terms (eg. 2; 3x; 7y) are not the same.You cannot add or subtract un-like terms. You can only leave them as they are.When multiplying things like x or y or z remember to do your 'powers'Examples:MULTIPLYING UN-LIKE TERMS-3n times 2m= 6mn (put letters in alphabetic order) or 5y times 4x= 20xy2. ADDING/SUBTRACTING LIKE AND UN-LIKE TERMS-You can add/subtract 7z+3z/ 7z-3z, = 10z/4z.3. DOING POWERS-x times x3= x4 because there is an 'invisible' 1 next to the first x.And 3x2 times 4x3 = 12x6

Dont trip B****
-3(x + y + z)
The GCF is 2yz.
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
3z+2= x ; z=53(5)+215+217Blake watson 63877
It is: 7xy/21yz = x/3z when simplified
It's rare to see an equation with two equals signs. I'm guessing something else went in between 3z and 9. 3z + 9 = 15, then z = 2 3z - 9 = 15, then z = 8 3z x 9 = 15, then z = 5/9 3z/9 = 15, then z = 45
(x + y + z)2 = x2 + y2 + z2 + 2xy + 2yz + 2zx
-47 + 6z = 3z-2-3z -3z-47 + 3z = -2+47 +473z = 45/3 /3z = 15
