My math problem is
-2(2+3)-2k = -2-4(2+2)
My answer is k=20 is this answer correct.
Quick mental calculation for you k = 20
LS = -10-40 = -50
RS = -2 - 16 = -18
nope, it is wrong.
Now show me what steps you had, so I can help you.
These are the steps after I
-4+-6-2k = -2-8 +-8
-10-2k = -2-8+-8
-2 = -18
k = 20
-2(2+3)-2k = -2-4(2+2)
-2(5)-2k = -2-4(4)
-10-2k = -2-16
-10-2k = -18
-2k = -18+10
-2k = -8
Divide both sides by (-2):
K = 4.

To solve this equation, let's simplify both sides step by step.
Starting on the left side:
-2(2+3) can be simplified by performing the operation inside the parentheses first, which gives us -2(5). Multiplying -2 by 5 yields -10.
So the left side becomes: -10 - 2k.
Now let's simplify the right side:
-4(2+2) can be simplified by performing the operation inside the parentheses first, which gives us -4(4). Multiplying -4 by 4 yields -16.
So the right side becomes: -2 - 16.
Now let's simplify both sides of the equation:
The original equation was: -10 - 2k = -2 - 16.
Combine like terms: -10 - 2k = -18.
To isolate the variable k, we will move the -10 to the right side by adding it to both sides of the equation:
-2k = -18 + 10.
Simplifying further: -2k = -8.
Now divide both sides of the equation by -2 to solve for k:
k = -8 / -2.
Simplifying the division: k = 4.
Therefore, the correct value of k is 4, not 20 as you stated.
