Answer:
[tex]x= -\frac{5}{8}[/tex] or [tex]-0.625[/tex].
Step-by-step explanation:
1. Write the expression.
[tex]15-2x=6x+20[/tex]
2. Substract 15 from both sides of the equation.
[tex]15-2x-15=6x+20-15\\ \\-2x=6x+5[/tex]
3. Substract 6x from both sides of the equation.
[tex]-2x-6x=6x+5-6x\\ \\-8x=5[/tex]
4. Divide by -8 on both sides of the equation.
[tex]\frac{-8x}{-8} =\frac{5}{-8} \\ \\x=-\frac{5}{8}[/tex]
5. Express your result.
[tex]x= -\frac{5}{8}[/tex] or [tex]-0.625[/tex].
