-
Equation tan(x)=5
- Express {x} in terms of y where:
- -11*x-1*y=12
- 3*x+19*y=4
- 8*x-9*y=-1
- -3*x-19*y=-9
-
Identical expressions
- nine - eight *x=- nine *x+ fifteen
- 9 minus 8 multiply by x equally minus 9 multiply by x plus 15
- nine minus eight multiply by x equally minus nine multiply by x plus fifteen
- 9-8x=-9x+15
-
Similar expressions

The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
We get the answer: x = 6
9-8*x = -9*x+15
Move free summands (without x)
from left part to right part, we given:
