Solving:
-7 + y = 3 + 2y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-2y' to each side of the equation.
-7 + y + -2y = 3 + 2y + -2y
Combine like terms: y + -2y = -1y
-7 + -1y = 3 + 2y + -2y
Combine like terms: 2y + -2y = 0
-7 + -1y = 3 + 0
-7 + -1y = 3
Add '7' to each side of the equation.
-7 + 7 + -1y = 3 + 7
Combine like terms: -7 + 7 = 0
0 + -1y = 3 + 7
-1y = 3 + 7
Combine like terms: 3 + 7 = 10
-1y = 10
Divide each side by '-1'.
y = -10
Hope it helps. (:

Answer:
Part a) The quadratic function is ![4x^{2} +20x-39=0](https://tex.z-dn.net/?f=4x%5E%7B2%7D%20%2B20x-39%3D0)
Part b) The value of x is
Part c) The photo and frame together are
wide
Step-by-step explanation:
Part a) Write a quadratic function to find the distance from the edge of the photo to the edge of the frame
Let
x----> the distance from the edge of the photo to the edge of the frame
we know that
![(6+2x)(4+2x)=63\\24+12x+8x+4x^{2}=63\\ 4x^{2} +20x+24-63=0\\4x^{2} +20x-39=0](https://tex.z-dn.net/?f=%286%2B2x%29%284%2B2x%29%3D63%5C%5C24%2B12x%2B8x%2B4x%5E%7B2%7D%3D63%5C%5C%204x%5E%7B2%7D%20%2B20x%2B24-63%3D0%5C%5C4x%5E%7B2%7D%20%2B20x-39%3D0)
Part b) What is the value of x?
Solve the quadratic equation ![4x^{2} +20x-39=0](https://tex.z-dn.net/?f=4x%5E%7B2%7D%20%2B20x-39%3D0)
The formula to solve a quadratic equation of the form
is equal to
in this problem
we have
![4x^{2} +20x-39=0](https://tex.z-dn.net/?f=4x%5E%7B2%7D%20%2B20x-39%3D0)
so
substitute in the formula
![x=\frac{-20(+/-)32} {8}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-20%28%2B%2F-%2932%7D%20%7B8%7D)
-----> the solution
Part c) How wide are the photo and frame together?
![(4+2x)=4+2(1.5)=7\ in](https://tex.z-dn.net/?f=%284%2B2x%29%3D4%2B2%281.5%29%3D7%5C%20in)
