Hi there!

Answer:

=2x

*The answer must have a positive sign.*

Step-by-step explanation:

<h2>Lesson: Using Properties to Simplify Expressions</h2>

First, you add/subtract by the numbers from left to right.

$3x-x=2x$

Then you use group like terms to change sides.

$2x+12-12$

Simplify and solve.

$12-12=0$

Final answer is 2x

I hope this helps you!

Have a nice day! :)

You need to combine like terms. So...

12 + 3x - x - 12 = 2x

Consider the function represented by 9x+3y= 12 with x as the independent variable. How can this function be written using

Ivenika [448]

Answer:

f(x)=-3x+4

(can't see some of your choices)

Step-by-step explanation:

We want x to be independent means we want to write it so when we plug in numbers we can just choose what we want to plug in for x but y's value will depend on our choosing of x.

So we need to solve for y.

9x+3y=12

Subtract 9x on both sides

3y=-9x+12

Divide both sides by 3:

y=-3x+4

Replace y with f(x).

f(x)=-3x+4

Y=-3x+27 6y-x+9=0 substitution

gayaneshka [121]

Answer:

x=9, y=0. (9, 0).

Step-by-step explanation:

y=-3x+27

6y-x+9=0

-----------------

6(-3x+27)-x+9=0

-18x+162-x+9=0

-19x+171=0

-19x=0-171

-19x=-171

19x=171

x=171/19

x=9

y=-3(9)+27=-27+27=0
