50 POINTS! PLEASE HELP!
Solve the equation with parentheses and variables on both sides of the equal sign.
5(x-4)+3x-9x=6-(2x+5)+8x
Part1: Use the distributive property to remove the parentheses.
Part2: Collect any like terms on both sides of the equation.
Part3: Bring all variable terms to one side of the equation. (Hint: Add x to both sides)
Part4: Bring all constant terms to one side. A constant term is a number without a variable. (Hint: Subtract 1 from both sides.)
Part5: Now solve the one-step equation. Show your work.

Step 1. Simplify brackets

[tex]5(x-4)+3x-9x=6-2x-5+8x[/tex]

Step 2. Simplify [tex]5(x-4)+3x-9x[/tex] to [tex]5(x-4)-6x[/tex]

[tex]5(x-4)-6x=6-2x-5+8x[/tex]

Step 3. Simplify [tex]6-2x-5+8x[/tex] to [tex]1+6x[/tex]

[tex]5(x-4)-6x=1+6x[/tex]

Step 4. Expand

[tex]5x-20-6x=1+6x[/tex]

Step 5. Simplify [tex]5x-20-6x[/tex] to [tex]-x-20[/tex]

[tex]-x-20=1+6x[/tex]

Step 6. Add [tex]x[/tex] to both sides

[tex]-20=1+6x+x[/tex]

Step 7. Simplify [tex]1+6x+x[/tex] to [tex]1+7x[/tex]

[tex]-20=1+7x[/tex]

Step 8. Subtract [tex]1[/tex] from both sides

[tex]-20-1=7x[/tex]

Step 9. Simplify [tex]-20-1[/tex] to [tex]-21[/tex]

[tex]-21=7x[/tex]

Step 10. Divide both sides by [tex]7[/tex]

[tex]- \frac{21}{7} =x[/tex]

Step 11. Simplify [tex] \frac{21}{7} [/tex] to [tex]3[/tex]

[tex]-3=x[/tex]

Step 12. Switch sides

[tex]x=-3[/tex]

Done! :)

[tex]Answer:[/tex]

[tex]x = -3[/tex]

[tex]Step-by-step~explanation:[/tex]

[tex]5x-20+3x-9x=6-(2x+5)+8x[/tex]

[tex]8x-20-9x=6-(2x+5)+8x[/tex]

[tex]-x-20=6-(2x+5)+8x[/tex]

[tex]-x-20=6-2x-5+8x[/tex]

[tex]-x-20=1-2x+8x[/tex]

[tex]-x-20=1+6x[/tex]

[tex]-x-20-6x=1[/tex]

[tex]-7x-20=1[/tex]

[tex]-7x=1+20[/tex]

[tex]-7x=21[/tex]

[tex]\frac{21}{-7}[/tex]

[tex]-3[/tex]
