5n+34=-2

解答

5 n + 34 = - 2

n = - \frac{36}{5}

十进制

n = - 7.2

求解步骤

5 n + 34 = - 2

将

34

到右边

5 n = - 36

两边除以

5

n = - \frac{36}{5}

a = 3 n + 1

so l v e f or x, y = f (1 + 2 x) + 3

\frac{( 3 a - 2 )}{3} + \frac{( 2 a + 3 )}{2} = a + \frac{7}{6}

so l v e f or x, 3 x_{2} y = 7

so l v e f or x, x + 7 y = c
