Let the side length of the original square be x, then
1/4 x^2 = (x - 3)^2
x^2 = 4(x^2 - 6x + 9) = 4x^2 - 24x + 36
3x^2 - 24x + 36 = 0
3(x^2 - 8x + 12) = 0
x^2 - 8x + 12 = 0
x^2 - 2x - 6x + 12 = 0
x(x - 2) - 6(x - 2) = 0
(x - 6)(x - 2) = 0
x - 6 = 0 or x - 2 = 0
x = 6 or x = 2
therefore, the side length of the original square is 6 inches.
Hope this helps!

Answer:
x=1
y=0.5
Step-by-step explanation:
-4x+3y=-2
<em>Add 4x to both sides</em>
3y=-2+4x
y=x-1
<em>Multiply both sides by 3</em>
3y=3x-1
Combine equations
-2+4x=3x-1
<em>Subtract 3x from both sides</em>
x-2=-1
<em>Add 2 both sides</em>
x=1
-4x+3y=-2
<em>Subtract 3y from both sides</em>
-4x=-2-3y
y=x-1
<em>Add 1 to both sides</em>
x=y+1
<em>Multiply both sides by -4</em>
-4x=y-4
Combine equations
y-4=-2-3y
<em>Add 3y to both sides</em>
4y-4=-2
<em>Add 4 to both sides</em>
4y=2
<em>Divide both sides by 4</em>
y=0.5
I hope it's right because this was very confusing.
