23=5-2y
Get y alone,
23-5= 18
18= -2y
Divide to find y
18/-2=-9
Y= -9
Or since you asked for x, X=no solutions.

Answer:
The lengths of the diagonals is 22.
Step-by-step explanation: Since the shape is a rectangle, the diagonals are congruent, we can form the equation 3x+7=5x-3.
Solve for x; 2x=10-->x=5.
Plug 5 into one of the equations. 3(5)+7=22. 5(5)-3=22

![x^3-7x^2+14x-8=(x-4)(x2-3x+2)\\=(x-4)[x^2-x-2x+2]\\=(x-4)[x(x-1)-2(x-1)]\\=(x-4)(x-1)(x-2)](https://tex.z-dn.net/?f=x%5E3-7x%5E2%2B14x-8%3D%28x-4%29%28x2-3x%2B2%29%5C%5C%3D%28x-4%29%5Bx%5E2-x-2x%2B2%5D%5C%5C%3D%28x-4%29%5Bx%28x-1%29-2%28x-1%29%5D%5C%5C%3D%28x-4%29%28x-1%29%28x-2%29)
x-intercepts are (4,0),(1,0),(2,0)
put x=0
y=-8
y -intercept is (0,-8)
