How to use it?
- Equation:
- Equation x=(4*a^4+1*a^4-104)/4
- Equation (4+x*9)-36=40
- Equation (9y-2)(2.1-7y)=0
- Equation x^2+6/5-8-x/10=0
- Express {x} in terms of y where:
- -1*x-19*y=-10
- 5*x+5*y=20
- 4*x-16*y=6
- sqrt(x^2+y^2+4x-6y-12)+(x^2+10x-27)=8-|y-9|+|y-3|

The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$9 x = 72$$
Divide both parts of the equation by 9
We get the answer: x = 8
(4+x*9)-36 = 40
Expand brackets in the left part
4+x*9-36 = 40
Looking for similar summands in the left part:
-32 + 9*x = 40
Move free summands (without x)
from left part to right part, we given:
$$9 x = 72$$
Divide both parts of the equation by 9
x = 72 / (9)
We get the answer: x = 8
