The equation
7 x + 14 y + 10 z = 98001
has infinite solutions. For any x and y we can have a z which satisfies this equation.
For example, if we choose x=1 and y=1 then z=9798 satisfies.
To have a specific solution there must be three equations for three unknowns (x,y,z), which can be solved simultaneously.

What is the product of 10 and z?
In algebra it is simply 10z
If 15x's equals 20y's and 16y's equals 10z's then 6x's equals how many z's?
15x = 20y16y = 10z6x = ? Reducing equation #1 says that x = 4/3yDoing the same to #2 says that y = 5/8zIf x=(4/3)y and y=(5/8)z then x must be (4/3)(5/8) = (4/8)(5/3) = (1/2)(5/3) = (5/6)If x=(5/6) then 6x = 5 ■
How many ways are there to make 14 cents?
The coins we know are:A penny - 1 centA nickel - 5 centsA dime - 10 centsA quarter - 25 centsLet x denote the number of pennies, y denote the number of nickels, z denote the number of dimes and w denote the number of quarter.We can set up the expression this way:x + 5y + 10z + 25w = 14But since we want to make 14 cents, quarters are not considered to be the part of the combination, so we write:x + 5y + 10z = 14There is no quick way to work out this problem. All you need to do is to work by trials.If we have y = 0 nickels and z = 1 dime, then the remaining choice is 4 pennies to make 14 cents.If we have y = 2 nickels and z = 0 dimes, then the remaining choice is also 4 pennies.If we have y = 1 nickel and z = 0 dimes, then the remaining choice is 9 pennies.If y = z = 0 of these coins - nickels and dimes - , then we can make 14 cents by 14 pennies.So there are 4 ways to form 14 cents.
3 times X?
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

Factors of y2 plus 10z - 10y - yz?
y2 + 10z - 10y - yz = y2 - 10y - yz + 10z = y(y - 10) - z(y - 10) = (y - 10)(y - z)
-6z plus 2 equals 3z plus 4z plus 28 How do you prove the answer -2 is correct?
-6z 2 = 3z+ 4z+28 -6z+2 +3z = 3z+ 4z +28 +4z -6z+4z+2 = 3z+ 28 -10z+2 -3z= 28 - 2 -10z + -3z = 26 -13z/13 = 26/-13 z = -2
What is 10 times z plus one?
Ten z plus one, or ten z plus ten. That depends on where you had parentheses in the original expression: (10 * z) +1 = 10z + 110 * (z + 1) = 10z + 10
What is the LCM 10z and 20z?
To find the LCM, you first need to express the numbers as the product of their prime factors. In this case: 10z = 2x5xz 20x = 2x2x5xz The next step is to identify the HCF. In this case that's 2x5xz = 10z. Then you multiply the numbers together and divide by the HCF: 10z x 20z/10z = 20z Thus the LCM of 10z and 20z is 20z.
What is the LCM of 10z and 20z?
Since 20z is a multiple of 10z, it is automatically the LCM of this problem.
What is the product of 10 and z?
In algebra it is simply 10z
What the value of 10Z when the value of z is 0.4?

What is the answer for adding polynomials 2z plus 3z plus 5z plus 4 plus 6x-2x?
We can simplify this expression by combining the like terms. Here the likes terms are the z's and the x's.2z + 3z + 5z = 10z. (If we have 2 of something and add three of the same thing and then 5 of the same thing we will end up with 10 of that thing).Likewise we can combine the x's.6x - 2x = 4x. (You could think of this as 6x + - 2x if this helps with the idea of "combining".)Therefore we are able to simplify this expression as:2z + 3z + 5z + 4 + 6x - 2x = 10z + 4 + 4x.
What is xy-2xz 5y-10z?
(x+5)(y-2z)
How many like terms are in the expression ten y plus ten z minus thirteen x minus four z plus ten plus two x y?
One pair, 10z and -4z, since like terms are only terms that contain the same variable(s) with the same exponent.
