Question

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

Answer 1

Answer:

$b = \frac{13}{12}$

Solution,

$b - \frac{7}{4} = \frac{ - 2}{3} \\ or \: \frac{b \times 4 - 7}{4} = \frac{ - 2}{ 3 } \\ or \: \frac{4b - 7}{4} = \frac{ - 2}{3} \\ or \: 3(4b - 7) = - 2 \times 4 \\ or \: 12b - 21 = - 8 \\ or \: 12b = - 8 + 21 \\ or \: 12b = 13 \\ \: b = \frac{13}{12}$

hope this helps...
