x+8=-6x
Multiply both sides of the equation by 2.
x+8+6x=0
Add 6x to both sides.
7x+8=0
Combine x and 6x to get 7x.
7x=-8
Subtract 8 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-8}{7}
Divide both sides by 7.
x=-\frac{8}{7}
Fraction \frac{-8}{7} can be rewritten as -\frac{8}{7} by extracting the negative sign.
