You can put this solution on YOUR website!
-8(2y-4)=9(4-2y)
\n" ); document.write( "This isnt so bad if we just remember the order of operations.
\n" ); document.write( "First let's use the distributive property on both sides of the equation...
\n" ); document.write( "Lets start with the left side:
\n" ); document.write( "-8(2y-4)
\n" ); document.write( "this means...
\n" ); document.write( "-8(2y)and -8(-4)= -16y + 32
\n" ); document.write( "then the right side:
\n" ); document.write( "9(4-2y)
\n" ); document.write( "this means
\n" ); document.write( "9(4) and 9(-2y)= 36 - 18y
\n" ); document.write( "so now our equation looks like...
\n" ); document.write( "-16y + 32 = 36 - 18y
\n" ); document.write( "now we need to arrange this equation so that the y variables are on the same side of the equation...
\n" ); document.write( "so if we add 18 y to both sides...
\n" ); document.write( "-16y + 18y + 32 = 36 - 18y + 18 y
\n" ); document.write( "which becomes...
\n" ); document.write( "2y + 32 = 36
\n" ); document.write( "now we can subtract 32 from both sides to isolate the y variable...
\n" ); document.write( "2y + 32 - 32 = 36 - 32
\n" ); document.write( "this becomes
\n" ); document.write( "2y = 4
\n" ); document.write( "Now in order to completely isolate the y variable we can divide both sides by 2
\n" ); document.write( "\"%282y%29%2F2+=+4%2F2\"
\n" ); document.write( "This becomes...
\n" ); document.write( "y = 2
\n" ); document.write( "this is the answer.
\n" ); document.write( "I hope this helps.
\n" ); document.write( "Good Luck!\r
