-(-(-)(-)(-10x))=-5 solve for x
A. X=.5
B. X=.7 repeating
C. X=-.5
D. X=1
Please help i am so confused.
10x = -5
has solution x = -0.5
-10x = -5
has solution x = 0.5
Now just count the = signs
an odd number will be -
an even number will be +
(on the left side)
dang! count the - signs (not the = signs!)
To solve the equation -(-(-)(-)(-10x)) = -5, we'll break it down step by step. Let's start by simplifying the innermost parentheses first.
Inside the innermost set of parentheses, we have (-10x). According to the order of operations (PEMDAS), we'll start by simplifying the multiplication:
-(-(-)(-)10x) = -(-(-)10x)
Next, we simplify the remaining parentheses:
-(-(-)10x) = -(-10x)
Now, we simplify the outermost set of parentheses:
-(-10x) = 10x
Now our equation becomes 10x = -5. To solve for x, we will isolate x by dividing both sides of the equation by 10:
10x = -5
Dividing by 10, we get:
x = -5/10
Simplifying the fraction, we find:
x = -1/2
So, the value of x that satisfies the equation is x = -1/2, which is option C: x = -0.5.
