please solve:
8y  12 < 7y  7
{ y y < ?
there is supposed to be a straight line between the y and y

subtract 7x from both sides
add 12 to each side.

do you mean subtract 7y from both sides? There is no 7x

math  bobpursley, Sunday, August 22, 2010 at 8:56pm
yes, 7y

math  barb, Sunday, August 22, 2010 at 9:05pm
8y12<7y7
8y 12 7y<7y77y
y12<7
y12+12<7+12
y<5
Is this correct?
