Answer:

Combine like terms

Step-by-step explanation:

The first step in such equations is to simplify the equation which is done most often by combining like terms, and by combining like terms i mean for example:

1 + 5 + 3x = 4y + z

You will combine the like terms (those that can be added or subtracted):

6 + 3x = 4y + z

In our example, combining terms would be adding 2x/3 and 1x/3 to give

3x/3 + 2 = 5

The equation is now simple and easy to solve as you simplify 3x/3 to 1x and then proceed to rearrange the equation to yield the value of x

Hope this helps!

How to write y-2=-1/3 (x+6) in standard form and why PLZ HELP

stich3 [128]

$y-2=-\frac{1}{3}(x+6)\\y=-\frac{1}{3}(x+6)+2$

Simply move -2 to another side.

$y=-\frac{x}{3}-2+2$

Distribute -1/3 in (x+6)

$y=-\frac{x}{3}$ ---> Answer

If the average of x and y is 11 and the average of x, and y z is 5 what is the value of z

qwelly [4]

If the average of x and y is 11 and the average of x, y and z is 5, then the value of z is -7

Given,

The average of x and y = 11

We know average = Sum of the terms / Number of terms

Then, the equation will become

$\frac{x+y}{2}=11$
x+y =11×2

x+y =22

Average of x, y and z = 5

$\frac{x+y+z}{3}=5$

x+y+z = 5×3

x+y+z =15

Substitute the value of x+y

22+z=15

z =15-22

x = -7

Hence, If the average of x and y is 11 and the average of x, y and z is 5, then the value of z is -7
