0.67 * 2,000 = 1340
Answer:
-(14 - 7x); 7(x - 2); 3x - 14 + 4x
Step-by-step explanation:
for -(14 - 7x) when the negative is distributed you get -14 + 7x which is still 7x - 14
for 7(x - 2) when multiplied in you get 7x - 14
for 3x - 14 + 4x when added together you get 7x - 14
So much more - es mucho mas
Answer:
Step-by-step explanation:
The given systems of equations is
The augmented matrix is
.
We perform the following row operations to reduce the matrix to reduced row echelon form using row 1 as our pivot row.
Next, we perform the following row operations using row 2 as our pivot row to obtain,
Next, we perform the following row operations using row 3 as our pivot row to get,
The matrix is now in the reduced row echelon form,
Therefore the solution is,
