方程 cos(4*x)=0
-
方程 x^2-21=4x
-
方程 5x-9=3x+1
-
方程 x:12=17
- 在方程中将 {x} 用 y 表示:
- -12*x+17*y=-11
- -8*x-16*y=18
- -10*x-19*y=3
- -17*x+1*y=19

等价表达式
- eight - one / seven * fourteen =y
- 8 减 1 除以 7 乘以 14 等于 y
- eight 减 one 除以 seven 乘以 fourteen 等于 y
- 8-1/714=y
- 8-1 除以 7*14=y
-
相似表达式

Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without y)
from left part to right part, we given:
$$0 = y - 6$$
Move the summands with the unknown y
from the right part to the left part:
$$- y = -6$$
Divide both parts of the equation by -1
We get the answer: y = 6
8-1/7*14 = y
Looking for similar summands in the left part:
6 = y
Move free summands (without y)
from left part to right part, we given:
$$0 = y - 6$$
Move the summands with the unknown y
from the right part to the left part:
$$- y = -6$$
Divide both parts of the equation by -1
y = -6 / (-1)
We get the answer: y = 6
