How to use it?
- Equation:
-
Equation x^3=3
-
Equation (x+3)^3=9*(x+3)
-
Equation (x-1)*(x+1)=0
-
Equation -2x^2+x+7=-x^2+5x+(-2-x^2)
- Express {x} in terms of y where:
- 8*x-9*y=-1
- -6*x+11*y=-5
- -3*x-19*y=-9
- 8*x-19*y=16

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:
$$7 x = 574$$
Divide both parts of the equation by 7
We get the answer: x = 82
4*x+3*(x+58) = 748
Expand brackets in the left part
4*x+3*x+3*58 = 748
Looking for similar summands in the left part:
174 + 7*x = 748
Move free summands (without x)
from left part to right part, we given:
$$7 x = 574$$
Divide both parts of the equation by 7
x = 574 / (7)
We get the answer: x = 82
