Is this right ?
-2(w-30) =-6w
-2w -60 = -6 w
+2w =+2w
-60 = -4w
_____________
-4 = -4
15 = w
Please rework this problem paying attention to the signs.
Remember that a negative times a negative is a positive.
Sorry should be -2w + 60 = -6w
-2w. = -2w
60/-4 = -4/-4w
-15= w
Is it right now ?
Yes.
Let's check if your solution is correct.
Starting equation: -2(w - 30) = -6w
We'll expand and simplify the equation step by step:
1. Distribute the -2 to the terms inside the parentheses:
-2w + 60 = -6w
2. Move all the terms involving "w" to one side of the equation:
-2w + 6w = -60
Combine like terms:
4w = -60
3. Divide both sides of the equation by 4 to isolate "w":
4w/4 = -60/4
Simplify:
w = -15
So, the correct solution is w = -15, not w = 15 as you have in your solution. Therefore, your solution is incorrect.
