4x+3y=7
3x-2y=9
12x+9y=21
12x-8y=36
^^Multiply top equation by 3 and multiply bottom equation by 4 
 12x+9y=36
- 12x-8y=36
 17y=-15
^^Then subtract those two new equations
17y/17= -15/17
Y= -0.88
^^Next divide both sides by 17 
4x+3* -0.88=7
 4x + (-2.64) =7
 -(-2.64) -(-2.64)
 4x = 9.64
 4x/4=9.64/4
 X=2.41
^^then choose on equation and put your new y in the y spot and solve. 
X=2.41 
Y=-0.88
Your point/coordinate is (2.41,-.88)

Using the scale ratio, the length of the dress is: 6 ft.
<h3>How to Apply Scale to Measurement?</h3>
Given a scale for the dress pattern as, 2 inches : 1 foot, it means 2 inches of the model equals 1 foot of the actual dress.
Therefore, using the scale ratio, let x represent the length of the dress. We would have:
2/1 = 12/x
x = (12 × 1)/2
x = 6 ft.
The length of the dress is: 6 ft.
