Answer:
a+B=c. x+8=17. x+8-8=17-8.
x=9
Answer:
y=12
Step-by-step explanation:
y=2x ,so 2x=8x-x^2
x^2=8x-2x
x^2=6x
x^2/x=6x/x
x=6
y=2x ,2(6)
y=12
X and Y can almost be any number and long as the statement 'equal to' is true the equation is correct.
So the division of a number and -9 or

+10=11 or
(x/-9)+10=11
subtract 10 from both sides
x/-9=1
multiply both sides by -9
x=-9
