Algebra.Com's Answer #504841 by josh_jordan(263)![]() ![]() You can put this solution on YOUR website! To find the value of a, we need to get a by itself on the left side of the equal sign. To do this, first add 5 to both sides of the equal sign:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "7a - 5 + 5 = 23 + 5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Combine like terms:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "7a = 28\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Finally, divide both sides of the equation by 7. This will give us the value of a:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "a = 4 \n" ); document.write( " |
