Algebra.Com's Answer #36023 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Solve for x: \n" ); document.write( "3x-5(3x-7) = 2(x+9)+45 First, apply the distributive property on both sides. \n" ); document.write( "3x-15x+35 = 2x+18+45 Now simplify this, \n" ); document.write( "-12x+35 = 2x+63 Add 12x to both sides of the equation. \n" ); document.write( "35 = 14x+63 Subtract 63 from both sides. \n" ); document.write( "-28 = 14x Finally, divide both sides by 14. \n" ); document.write( "-2 = x or x = -2 \n" ); document.write( " |
