solvefor x,(f\circ g)=x+7

解答

求解

x, (f \circ g) = x + 7

x = \circ f g - 7

求解步骤

(f \circ g) = x + 7

交换两边

x + 7 = f \circ g

x + 7 = \circ f g

将

7

到右边

x = \circ f g - 7

6 x - 5 = 13

\frac{3 h}{10} - h = \frac{3}{2} - \frac{h}{5}

n x + 6 = 8 x + 10

- 10 - \frac{8 e - 3 e}{4 e} = 2 (e - 3)

so l v e f or x, 15 x - 8 y = 52
