5−(2w−8)=6w−9
Show Steps
Expand 5−(2w−8): −2w+13
−2w+13=6w−9
Subtract 13 from both sides
−2w+13−13=6w−9−13
Simplify
−2w=6w−22
Subtract 6w from both sides
−2w−6w=6w−22−6w
Simplify
−8w=−22
Divide both sides by −8
−8w
−8 =

Answer: Hotdog cost $0.75
Price of soda = $0.55
Step-by-step explanation:
Let the price of hot dogs be x.
Let the price of sodas be y.
6x + 4y = 6.70 ...... i
4x + 3y = 4.65 ....... ii
Multiply equation i by 4
Multiply equation ii by 6
24x + 16y = 26.80 ........ iii
24x + 18y = 27.90 ......... iv
Subtract iii from iv
2y = 1.10
y = 1.10/2
y = $0.55
Price of soda = $0.55
From equation i,
6x + 4y = 6.70
6x + 4(0.55) = 6.70
6x + 2.20 = 6.70
6x = 6.70 - 2.20
6x = 4.50
x = 4.50/6
x = $0.75
Hotdog cost $0.75
