Hello!

[tex]\large\boxed{\text{C.} \frac{-15}{2}}[/tex]

3x + 5 = x - 10

Solve for x by isolating the variable.

Subtract 5 from both sides:

3x + 5 - 5 = x - 10 - 5

3x = x - 15

Subtract x from both sides:

3x - x = x - x - 15

2x = -15

Divide both sides by 2:

2x /2 = -15 / 2

x = -15/2.

Answer:

-15/12

Step-by-step explanation:

move the variables 3x-x+5=-10 and collect like terms 3x-5=-10-5 and divide both sides 2x=-15

x=-15/12
