solvefor b,8b+qb=F

解答

求解

b, 8 b + q b = F

b = \frac{F}{8 + q}; q \neq = - 8

求解步骤

8 b + q b = F

分解

8 b + q b : b (8 + q)

b (8 + q) = F

两边除以

8 + q; q \neq = - 8

b = \frac{F}{8 + q}; q \neq = - 8

2 n - \frac{7}{3} n = \frac{5}{9}

\frac{x - 4}{2} = \frac{x + 2}{4}

so l v e f or A, 6 = - G + \frac{1}{5} r A

1 - \frac{5}{7} n = 11

so l v e f or F, F + ba = g a
