2x + y - (x + y) = 3z - 6z
--------------------------------------------------------
<span>x = -3z </span>
------------------------------------------
<span>(-3z, 9z) </span>
----------------------------------
<span>(x,y,z) = (-3z, 9z, z)
</span>--------------------------
<span>x = -3z, y = 9z
---------------------
There for the answer is </span><span>(-3z, 9z) </span>
Answer:
2/8, 4,16
Step-by-step explanation:
In maths, f (x) means as a special relationship where every single input has one output.
<u>Step-by-step explanation:</u>
In mathematics, a function is any expression that gives exactly one answer for each particular number. Input is the number provided in the expression, and output is the number obtained from the search or calculation.
In an ordered pair, input’s first number corresponds to the horizontal axis, and output’s second number in the vertical axis. These ordered pairs can then be plotted. Some data on the costs associated with this are called relationships. For example,
It is often written as "f (x)" where x is the input value and is the output value.

<span>The first and last four numbers each have a difference of one between them.
The fifth number has a difference of 10 between it and the previous number.
The middle number has a difference of 20 between itself and the two numbers that surround it.
Counting in this way could have been a result of a lot of things to count, and spot checking along the way (when the numbers have a difference of 1).</span>
