17 = -13 - 8x

First, add '13' to both of the sides.

17 + 13 = -8x
Second, add 17 + 13 to get 30.

30 = -8x
Third, divide both sides by '-8'.

(30)/(-8) = x
Fourth, change the fraction into a negative.

-(30)/(8) = x
Fifth, find the GCF of 30 and 8.
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Factors of 8: 1, 2, 4, 8
The GCF is 2.
Sixth, divide the numerator by the GCF.

30 ÷
2 = 15
Seventh, divide the denominator by the GCF.

8 ÷
2 = 4
Eighth, combine your new numerator and denominator.

- (15)/(4) = x
Ninth, switch your sides.

x = -(15)/(4)

Answer as fraction:
-(15)/(4)
Answer as decimal: -3.75
