If you use the distributive property, you will multiply 4 by 2x to get 8x and 4 by -4 to get -16.
8x-16=8x+k
If you want infinitely many solutions the equations on both sides of the equal sign need to be the same. So, k would need to be -16.
Answer:
w=6
Step-by-step explanation:
Simplifying
3(2w + 8) = 60
Reorder the terms:
3(8 + 2w) = 60
(8 * 3 + 2w * 3) = 60
(24 + 6w) = 60
Solving
24 + 6w = 60
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '-24' to each side of the equation.
24 + -24 + 6w = 60 + -24
Combine like terms: 24 + -24 = 0
0 + 6w = 60 + -24
6w = 60 + -24
Combine like terms: 60 + -24 = 36
6w = 36
Divide each side by '6'.
w = 6
Simplifying
w = 6
