Question

Solve the equation for w.

2w + 6 + 0.3w = −0.7w − 12
A: w = 6
B: w = 0
C: w = −6
D: No solution

Answer 1

Answer:w-6

Explanation:

2.3w+6=-0.7w-12

23w+60=-70w-120

23w=-70w-180

30w = -60

w=-60

Answer 2

C; w = -6

Explanation:

1. 2w + 6 + 0.3w = -0.7w - 12
2. 2.3w + 6 = -0.7w - 12 (Combine like terms)
3. 3w + 6 = -12 (I added 0.7w to each side)
4. 3w = -18 (Subtract 6 on each side)
5. w = -6 (Isolate the variable by using inverse operations)

Answer: w = -6

Hope this helped! :D
