Question 1130928

if you have this:

{{{-1/8+(9/2)y=-7/4 }}}

{{{(9/2)y=1/8-7/4 }}}

{{{(9/2)y=1/8-(7*2)/(4*2) }}}

{{{(9/2)y=1/8-14/8 }}}

{{{(9/2)y=-13/8 }}}

{{{y=-(13/8)/(9/2) }}}

{{{y=-(13/cross(8)4)/(9/cross(2)1) }}}

{{{y=-(13/4)/9 }}}

{{{y=-13/36 }}}



but, in case you have this:

{{{-1/8+9/(2y)=-7/4 }}}

{{{9/(2y)=1/8-7/4 }}}

{{{9/(2y)=-13/8 }}}

{{{8*9=-13*(2y) }}}

{{{-26y=72 }}}

{{{y=72/-26 }}}

{{{y= -36/13 }}}
