Solve for x. [tex]-2(x+3y)=18[/tex] Distribute the Parenthesis.How? Multiply all of the terms inside the parenthesis by the number outside the parenthesis. [tex](-2)*x+(-2)*3y=18[/tex] [tex]-2x-6y=18[/tex] Add 6y to both sides. [tex](-2x-6y)+6y=(18)+6y[/tex] [tex]-2x=18+6y[/tex] Divide both sides by -2. [tex](-2x)/-2=(18+6y)/-2[/tex] The Answer Is: [tex]x=-9-3y[/tex] [tex]x=-3y-9[/tex]
