in the urban ecosystem, the air is always is so much pollute, the waters too are always so much polluted hence not so much good for non human life. but in the undeveloped forest ecosystem, the air is so much fresh, the environment and the waters too hence find it better in the place.

The value of y for the system of equation is -1/2 .
<h3>What is a System of Equation ?</h3>
A system of equation is a set of equation that have common solution
The set of equation given is
3x+4y=4
2x−4y=6
To solve the system , Elimination method will be used
Add equation 1 and 2 to eliminate y
5x = 10
x = 2
Substitute the value of x in equation 1 to determine y
3x +4y = 4
6 + 4y = 4
4y = -2
y = -1/2
Therefore the value of y for the system of equation is -1/2 .

The given statement is false.
What is the effect of a row operation on a determinant?
The factor by which a row operation intends to change the determinant is not equal to the determinant of the elementary matrix corresponding to that row operation. Rather, when a row is scaled up by a factor in a matrix, the determinant of that matrix also scales up by that factor.
Similarly, the factor by which a row operation changes the determinant is equal to the factor times the determinant of the elementary matrix corresponding to that row operation.
