5x- 3(x-5)=13

5x-3x+15=13

2x=-2

Your mistake is that you forgot to add when you multiply 3 and 5

Answer:

None of those options

Step-by-step explanation:

I just did the work myself and even ran it through a calculator but the correct answer isn't one of those options. Here's my work:

$-\frac{5}{6} =z+\frac{1}{8}\\-\frac{5}{8}-\frac{1}{8}=z\\-\frac{40}{48}-\frac{6}{48}=z\\-\frac{46}{48}=z\\-\frac{23}{24}$

I'd contact you teacher about that...it might be an error in their system (it's happened to me a few times before where the correct answer is marked as incorrect or isn't even an option)

Solve for x: 3x - 3 - 6x = 12

Natalka [10]

Answer:

x = - 5

Step-by-step explanation:

3x - 3 - 6x = 12

group like terms

3x - 6x - 3 = 12

add similar elements

- 3x - 3 = 12

add 3 to both sides

- 3x - 3 + 3 = 12 + 3

simplify

- 3x = 15

divide both sides by 3

- 3x / 5 = 15 / - 3

simplify

x = - 5
