Algebra.Com's Answer #582286 by addingup(3677)![]() ![]() You can put this solution on YOUR website! R = S+5 \n" ); document.write( "4S+3 = 3R-2 and since we just said that R= S+5: \n" ); document.write( "4S+3 = 3(S+5)- 2 Let's multiply on the right to clear the parenthesis: \n" ); document.write( "4S+3 = 3S+15-2 Subtract on the right: \n" ); document.write( "4S+3 = 3S+13 Now subtract 3S on both sides, and also subtract 3 on both sides \n" ); document.write( "S = 10 Sheila is 10 years old. And Richard? Well, the problem says he's 5 years older than Sheila, so Richard is 15.\r \n" ); document.write( "\n" ); document.write( "Proof: \n" ); document.write( "4S+3 = 3R-2 \n" ); document.write( "4(10)+3 = 3(15)-2 \n" ); document.write( "43 = 43 We got the right answer. \n" ); document.write( " |
