Answer:
Step-by-step explanation:
y= -5x/2+1
Answer:
x = 3
Step-by-step explanation:
![\sqrt{2x - 6} = 3 - x](https://tex.z-dn.net/?f=%5Csqrt%7B2x%20-%206%7D%20%20%3D%203%20-%20x)
Square both sides of the equation
![2x - 6 = (3 - x)^{2} = 9 - 6x + x^{2} \\](https://tex.z-dn.net/?f=2x%20-%206%20%3D%20%283%20-%20x%29%5E%7B2%7D%20%3D%209%20-%206x%20%2B%20x%5E%7B2%7D%20%5C%5C)
![x^{2} - 8x + 15 = 0\\](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20-%208x%20%2B%2015%20%3D%200%5C%5C)
(x - 3)(x - 5) = 0
x = 3 or 5
Now, you must always check your results because a result may not satisfy the original equation.
If x = 3, then
and 3 - x = 3 - 3 = 0
So 3 satisfies the original.
If x = 5, then
, but 3 - x = 3 - 5 = -2. Therefore, 5 does NOT satisfy the original equation.
That means that x = 3 is the solution to the equation.
