Algebra.Com's Answer #57357 by sofiyacherni(99) ![]() You can put this solution on YOUR website! from the second equation \n" ); document.write( "*** y=2x/3-8/3=(2x-8)/3 \n" ); document.write( "substitute this for y in first equation \n" ); document.write( "x/5+1/2((2x-8)/3)=4 \n" ); document.write( "x/5+(2x-8)/6=4 \n" ); document.write( "find common denominator (by multiplying x/5 times 6 and (2x-8)/6 times 5, since 30 would be the common denominator) \n" ); document.write( "so you get \n" ); document.write( "(6x+10x-40)/30=4 \n" ); document.write( "16x-40=120 \n" ); document.write( "16x=160 \n" ); document.write( "x=10 \n" ); document.write( "now substite this value for x in equation marked *** \n" ); document.write( "now you have \n" ); document.write( "y=(2(10)-8)/3=(20-8)/3=12/3=4\r \n" ); document.write( "\n" ); document.write( "thus x=10 and y=4\r \n" ); document.write( "\n" ); document.write( "Good Luck! \n" ); document.write( " |
