ex+f = c -dx
ex+dx = c -f
x(e+d) = c -f
x = c -f/(e+d)
That is an impossible equation, because it is stating that m has two values.
Your question does not make sense. It would probably be interpreted as a + = ++a ---a
x = (d-a)/(a-c)

You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
An equation where x equals 3.
Yes that is correct
x=0
It is an equation and the value of n is 9
15x minus 8=minus 180 3x+8=24
By including its plus or minus signs
7
the y-1 is a minus .
{-1,7}
the answer is y minus 10 divided by 2.
X=-3
