h(7)=6(7)-7

解答

h (7) = 6 (7) - 7

解答

h = 5

求解步骤

h (7) = 6 (7) - 7

去除括号:

(a) = a

h (7) = 6 \cdot 7 - 7

数字相乘:

6 \cdot 7 = 42

h (7) = 42 - 7

数字相减:

42 - 7 = 35

h (7) = 35

流行的例子

3 - 2 x = 4 (x + 15)

1-1.7x-(0.8x+2)=3.4

1 - 1.7 x - (0.8 x + 2) = 3.4

2 x + 6 = 90

10 - 1.4 x = 10.84

- \frac{x}{3} + 1 \leq 3
