Solve the system by finding x, y, and z.

x-y+z=1
x+y+3z=-3
2x-y+2z=0

The solution is

Step-by-step explanation:

Given:

The system of equations given are:

Add first and second equations. This gives,

Adding equations 2 and 3, we get

We need solve equations 4 and 5.

Multiplying equation (4) by -3, we get

Adding the above equation to equation (5), we get

Now, we plug in in equation (4). This gives,

Now, we plug in in equation (1). This gives,

Therefore, the solution is

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

it goes right
