Algebra.Com's Answer #38722 by funmath(2933)![]() ![]() ![]() You can put this solution on YOUR website! b+4b=-90 Simplify both sides of the equal sign as much as you can. \n" ); document.write( "(1+4)b=-90 Combine like terms. \n" ); document.write( "5b=-90 \n" ); document.write( "5b/5=-90/5 To get the b isolated divide both sides by it's coefficient, 5. \n" ); document.write( "b=-18 \n" ); document.write( ": \n" ); document.write( "Check by substituting b=-18 into the original equation and simplifying to see if both sides equal when b=-18. \n" ); document.write( "(-18)+4(-18)=-90 \n" ); document.write( "-18-72=-90 \n" ); document.write( "-90=-90 It checks out, we're right!!! \n" ); document.write( "Happy Calculating!!! \n" ); document.write( " |
