Question 1090987
<font color="black" face="times" size="3">
I'm assuming the original equation is {{{expr(3/4)w + 5 = expr(1/2)w + 9}}}


If that is the case, then yes it leads to {{{expr(1/4)w = 4}}}; however, the answer is not {{{w = 1}}}


Instead the answer is {{{w = 16}}} because you multiply both sides by 4


{{{expr(1/4)w = 4}}}


{{{4*expr(1/4)w = 4*4}}}


{{{cross(4)*expr(1/cross(4))w = 16}}} Notice the '4's on the left side divide and cancel out (since 4/4 = 1)


{{{w = 16}}}


-------------------------------------------------------


Let's check the answer


{{{expr(3/4)w + 5 = expr(1/2)w + 9}}}


{{{expr(3/4)*16 + 5 = expr(1/2)*16 + 9}}} Replace every w with 16


{{{12 + 5 = 8 + 9}}}


{{{17 = 17}}}


The answer checks out.
