Answer:
x =
Step-by-step explanation:
Given
y = ← multiply both sides by (5x - 2)
y(5x - 2) = 2x + 3 ← distribute left side
5xy - 2y = 2x + 3 ( add 2y to both sides )
5xy = 2x + 3 + 2y ( subtract 2x from both sides )
5xy - 2x = 3 + 2y ( factor out x from each term on the left side )
x(5y - 2) = 3 + 2y ← divide both sides by (5y - 2)
x =
1 pound = 16 ounces
1 x 3 pounds = 16 x 3 ounces
3 pounds = 48 ounces
48 ounces > 46 ounces

The row echelon form of the matrix is presented as follows;
<h3>What is the row echelon form of a matrix?</h3>
The row echelon form of a matrix has the rows consisting entirely of zeros at the bottom, and the first entry of a row that is not entirely zero is a one.
The given matrix is presented as follows;
The conditions of a matrix in the row echelon form are as follows;
- There are row having nonzero entries above the zero rows.
- The first nonzero entry in a nonzero row is a one.
- The location of the leading one in a nonzero row is to the left of the leading one in the next lower rows.
Dividing Row 1 by -3 gives:
Multiplying Row 1 by 2 and subtracting the result from Row 2 gives;
Subtracting Row 1 from Row 3 gives;
Adding Row 2 to Row 3 gives;
Dividing Row 2 by -2, and Row 3 by 18 gives;
The above matrix is in the row echelon form
