4x + 8y = 30.60
Solving
4x + 8y = 30.60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation.
4x + 8y + -8y = 30.60 + -8y
Combine like terms: 8y + -8y = 0
4x + 0 = 30.60 + -8y
4x = 30.60 + -8y
Divide each side by '4'.
x = 7.65 + -2y
Simplifying
x = 7.65 + -2y</span>

Answer:

Step-by-step explanation:
If the rectangle show one side of length 5 x +2, and another side of length x - 4, then the area of this rectangle (given by the product of the sides' length) is:

which is already written in standard form.
You would subtract y on both sides so z-y then you get x=x. I think I hope this helps.
X intercepts (15,0)
Y intercepts (0,15)
Y=-x+15
X=-y+15
Slope=-1
Hope this helps!
