Answer:

[tex]\boxed {\boxed {\sf x= -13}}[/tex]

Step-by-step explanation:

We are asked to solve the following one-step equation.

[tex]-104 = 8x[/tex]

We solve the equation by solving for x. We must isolate the variable by performing the inverse operation.

x is being multiplied by 8 (8x = 8*x). The inverse operation of multiplication is division. Divide both sides of the equation by 8. This eliminates the 8 on the right side of the equation so only x remains.

[tex]\frac {-104}{8}= \frac{8x}{8}[/tex]

[tex]\frac {-104}{8}= x[/tex]

[tex]-13=x[/tex]

We can check our answer by substituting it back into the original equation.

[tex]-104= 8x[/tex]

[tex]-104= 8(-13)[/tex]

[tex]-104= -104[/tex]

This checks out, so we know our answer is correct and x is equal to -13.
