Question

B-7/4=-2/3 what does b equal

Answer 1

`b = (13)/(12)`

Solution,

`b - (7)/(4) = ( - 2)/(3) \\ or \: (b * 4 - 7)/(4) = ( - 2)/( 3 ) \\ or \: (4b - 7)/(4) = ( - 2)/(3) \\ or \: 3(4b - 7) = - 2 * 4 \\ or \: 12b - 21 = - 8 \\ or \: 12b = - 8 + 21 \\ or \: 12b = 13 \\ \: b = (13)/(12)`

hope this helps...
