in order to solve an equation for x, you must make sure that x is alone, in this case it is not, there is a (-) before it, remember, you have to do the same operation on each side of the equation to make it equivalent to the first equation.
if -x=1
x=(-)1
x=-1
x=1
x = 1/3
8+-1= 7 x=-1
Add 1 to both sides and you get y + 1 = X
x + 1= -y implies x - y = 1
-x = 1/2Multiply each side by -1 :x = -1/2
i have no clue what the answer is
It could be either, depending on what x equals. If x = 9, 8 will solve the first one. If x = 1, 8 will solve the second one.
5 + (-4) = 1 x = -4
X=1
It can be anything. Example: x=1
x=8
