c(x)=762.75+203.4x

解答

c (x) = 762.75 + 203.4 x

x = \frac{15255}{4 ( 5 c - 1017 )}; c \neq = \frac{1017}{5}

求解步骤

c (x) = 762.75 + 203.4 x

在两边乘以

100

c x \cdot 100 = 76275 + 20340 x

将

20340 x

para o lado esquerdo

c x \cdot 100 - 20340 x = 76275

分解

c x \cdot 100 - 20340 x : 20 x (5 c - 1017)

20 x (5 c - 1017) = 76275

两边除以

20 (5 c - 1017); c \neq = \frac{1017}{5}

x = \frac{15255}{4 ( 5 c - 1017 )}; c \neq = \frac{1017}{5}

- 2 x = - 8 x - 3

x = 3 (x - a)

- \frac{5}{6} x - \frac{1}{9} = - 102

- 4 (3 x + 6) - x = - 44 - 5 (2 x - 4)

S = 0. 5^{2} - 1.5 + 12.5
