7d-4 (d+8) = -8
???
When I did this equation I got 8=d
I know I did something wrong.
I just don't know any other way to do it.
I did basic equation-solving rules and got his answer. Help?
7 d - 4 d - 32 = -8
3 d = 24
d = 8
Thank you :3
You are welcome.
To solve the equation 7d-4(d+8) = -8, we need to simplify the expression and then isolate the variable 'd'.
First, let's simplify the expression within the parentheses by distributing the -4 to both terms inside the parentheses:
7d - 4(d+8) = -8
7d - 4d - 32 = -8
Now, combine like terms:
3d - 32 = -8
Next, we want to isolate the variable 'd', so let's add 32 to both sides of the equation to get rid of the -32:
3d - 32 + 32 = -8 + 32
3d = 24
Finally, divide both sides of the equation by 3 to solve for 'd':
3d/3 = 24/3
d = 8
So the correct answer is d = 8, which differs from the initial incorrect answer of d = -8.
