- Express {x} in terms of y where:
- -20*x-6*y=4
- -13*x+7*y=-15
- 5*x-14*y=-15
- -12*x-10*y=-16
- Equation:
-
Equation x^2+3x+2=0

The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$- 20 x = 6 y + 4$$
Divide both parts of the equation by -20
We get the answer: x = -1/5 - 3*y/10
-20*x-6*y = 4
Looking for similar summands in the left part:
-20*x - 6*y = 4
Move the summands with the other variables
from left part to right part, we given:
$$- 20 x = 6 y + 4$$
Divide both parts of the equation by -20
x = 4 + 6*y / (-20)
We get the answer: x = -1/5 - 3*y/10

$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{10} - \frac{3 i \operatorname{im}{\left(y\right)}}{10} - \frac{1}{5}$$
x1 = -3*re(y)/10 - 3*i*im(y)/10 - 1/5
