Step-by-step explanation:
Firstly, there's a typing error at (x=1)². I assume it is (x-1)². If my assumption is correct,then:
x²-2x+1-4x=x²-2x+1
x²-6x+1-x²+2x-1=0
-4x=0
x=0

Answer:
x = 7
Step-by-step explanation:
The equation can be rewritten to ...
8x = 13n +4 . . . . for some integers x and n
x = (13n +4)/8
For x to be an integer, 13n must be an odd multiple of 4. Since 13 is an odd number, n=4 will do.
x = (13·4 +4)/8 = 56/8
x = 7
__
The graph shows a "trial and error" method of solution. Only values of x less than 13 need to be examined.
Answer:
3
Step-by-step explanation:
I think its 3 because when we add 2 to x the graphic must be continue two step to right
Yes, since the other two numbers on each side are the same, any number can fit well in this equation.
