Solve the system by substitution.<br><br> 6x + 3y = -6<br> 2x + y = -2
Mariana [72]
Solutions 

First Lets solve for this equation 6x + 3y = -6&#10; 

6x + 3y = -6&#10; 

6x+3(-2-2x)=-6&#10;&#10; &#10; 

-6=-6 

Therefore this given equation is a <span>dependent system.

<span>Solve for </span>2x + y = -2 

2x+y=-2 

y=-2-2x&#10;&#10; &#10;&#10; &#10; 

There are too many solutions to these equations.

Here is a balanced hanger diagram
suter [353]

Based on the mass of the circle and the triangle, we can find the mass of the square to be<u> 3.33 grams</u>

<h3>Mass of each side of hanger </h3>

Assuming the mass of the square is x, the equation for the first side is:

= (3 x mass of circle) + (2 x mass of triangle) + (6 x mass of square)

= ( 3 x 2) + ( 2 x 4) + ( 6 × x)

= 6 + 8 + 6x

Mass of other side:

=  (2 x mass of circle) + (5 x mass of triangle) + (3 x mass of square)

= ( 2 x 2) + ( 5 x 4) + ( 3 × x)

= 4 + 20 + 3x

<h3>Mass of square </h3>

As both sides are equal, equate both formulas to find x:

6 + 8 + 6x = 4 + 20 + 3x

6x - 3x = 24 - 14

3x = 10

x = 10/3

x = 3.33 grams

In conclusion, each square is 3.33 grams.
