There are 3 available methods - Substitution , Elimination and <span>Matrix.  

</span>The substitution<span> method is used to eliminate one of the variables by replacement. 
</span>
The elimination method<span> is used for solving linear systems. 
</span>
<span>A Matrix is an array of numbers. 
</span>
<span>Lets use Substitution to solve this system.  
</span>
x+3y=0 

x=-3y&#10;&#10;&#10; 

Substitute x=-3y into <span>2x+6y=12 </span><span>

</span>2x+6y=12 

2*-3y+6y=12 

0=12

This graph will start at (.5, 0) as the vertex.

To find this, all you need to do if find the point where inside the absolute value sign is equal to 0. Since the graph can never have a negative value, this will be the lowest point.

2x - 1 = 0

2x = 1

x = .5

From there, you can plot each point by going up two and to the left one.

Examples of Points: (1.5, 2) and (2.5, 4)

You can also plot the other side of the graph by going up two and to the right one.

These points can be found using the slope, which is the number attached to x (2).

Example of Points (-.5, 2) and (-1.5, 4).

180+8x=160+6x help me find x
lianna [129]

Answer:

x = -10

Step-by-step explanation:

Step 1: Write equation

180 + 8x = 160 + 6x

Step 2: Solve for <em>x</em>

  1. Subtract 6x on both sides: 180 + 2x = 160
  2. Subtract 180 on both sides: 2x = -20
  3. Divide both sides by 2: x = -10

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

180 + 8(-10) = 160 + 6(-10)

180 - 80 = 160 - 60

100 = 100
