How to use it?
- Equation:
-
Equation sin(x)=cos(x)
-
Equation cos(x/2)=1/2
-
Equation sin(x)=√3/2
-
Equation sin(x)=1,5
- Express {x} in terms of y where:
- 12*10^(-30)-0,1884*10^12*x^2-y(0,3768*10^12*x+1,183152*10^12*x^3)+y^2(2,760688*10^24*x^2)=0=0
- (x^2+y^2)×(x+y-3)=2xy
- sqrt(1-x)^2+(4-y)^2=0
- lnx+sin(y/x+2x)=4
-
Identical expressions
- (one , two -x)+ one = one , eight
- (1,2 minus x) plus 1 equally 1,8
- (one , two minus x) plus one equally one , eight
- 1,2-x+1=1,8
-
Similar expressions

The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- x = - \frac{2}{5}$$
Divide both parts of the equation by -1
We get the answer: x = 2/5
((6/5)-x)+1 = (9/5)
Expand brackets in the left part
6/5-x)+1 = (9/5)
Expand brackets in the right part
6/5-x)+1 = 9/5
Looking for similar summands in the left part:
11/5 - x = 9/5
Move free summands (without x)
from left part to right part, we given:
$$- x = - \frac{2}{5}$$
Divide both parts of the equation by -1
x = -2/5 / (-1)
We get the answer: x = 2/5
