8y - 12 < 7y - 7

{ y y < ?
there is supposed to be a straight line between the y and y

• math -

subtract 7x from both sides

• math -

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

• math -

yes, 7y

• math -

8y-12<7y-7
8y -12 -7y<7y-7-7y
y-12<-7
y-12+12<-7+12
y<5

Is this correct?

• math -

mucho correct.
