solvefor a, 2/3 b+5a= 1/2 b-1/6

解答

求解

a, \frac{2}{3} b + 5 a = \frac{1}{2} b - \frac{1}{6}

解答

a = \frac{- b - 1}{30}

求解步骤

\frac{2}{3} b + 5 a = \frac{1}{2} b - \frac{1}{6}

将

\frac{2}{3} b

到右边

5 a = - \frac{1}{6} b - \frac{1}{6}

两边除以

5

a = \frac{- b - 1}{30}

- 2.1 (m - \frac{3}{4}) = - 7

- (3 k - 12) = 48

solvefor a,R=m(a+g)

so l v e f or a, R = m (a + g)

x + 3 (x - 2) = 2 x - 4

2(3x-2)-5x=2(x-3)+90

2 (3 x - 2) - 5 x = 2 (x - 3) + 90
