Algebra.Com's Answer #90103 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let M = McGoo's present age and G = Gomer's present age. \n" ); document.write( "From the problem, you can write: \n" ); document.write( "1) M = 8G \"McGoo is 8 times as old as his son, Gomer\" \n" ); document.write( "2) M+3 = 5(G+3) \"In three years, he (M) will be five times his son's (G's) age\" \n" ); document.write( "Substitute the M = 8G from equation 1) into equation 2) and solve for G. \n" ); document.write( "2a) (8G)+3 = 5(G+3) Simplify. \n" ); document.write( "8G+3 = 5G+15 Subtract 5G from both sides. \n" ); document.write( "3G+3 = 15 Subtract 3 from both sides. \n" ); document.write( "3G = 12 Finally, divide both sides by 3. \n" ); document.write( "G = 4 \n" ); document.write( "Gomer is 4 years old.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
