Question 916800

{{{ (8a + 4) /( 8a + 6) = 2 /4 }}} ....cross multiply


{{{4(8a + 4)  = 2( 8a + 6) }}}


{{{4*8a + 4*4  = 2*8a + 2*6 }}}


{{{32a + 16 = 16a + 12 }}}


{{{32a- 16a+ 16 = 16a -16a+ 12 }}}


{{{32a- 16a+ 16-16 =  12-16 }}}


{{{32a- 16a =  12-16 }}}


{{{ 16a = -4 }}}


{{{ a = -4/16 }}}


{{{ a = -(4:4)/(16:4) }}}


{{{ a = -1/4 }}}
