Help please i’ll give brainiest

 second and fourth choices have infinitely many solutions

Step-by-step explanation:

When you combine the like terms in those two equations you end up with an "identity." Both sides of the equation are the same.

x - 1/3(3x) = 0 . 1/3 of 3x is 1x

x - x = 0  any number minus itself is 0

or add x to both sides  x-x+x = 0 + x  

x = x is an identity. An identity has infinite solutions.

3x + 2 - 1/3(3x) = 2 + 2x

3x + 2 -x = 2 + 2x

2x +2 = 2 + 2x . same thing! Infinite solutions.

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
