First account: $6500
Second account: $8500
Set x is amount of money in first account
=> x + 2000 is money in second account.
X*3% + (x+2000)*4% = 535
=> x = (53500 - 8000) / 7
X = 45500 / 7 = 6500
=> account #1 = x = 6500
Acc #2 = x + 2000 = 6500 + 2000 = 8500
Answer: First, turn the mixed fraction 16 1/4 into a improper fraction. It would become 65/4
x+65/4=64
Next, I would multiply the entire equation by 4 to get rid of the fraction
It would become 4x+65=256
Now solve for X
4x=191
x=191/4
x=47.75
Step-by-step explanation:
Answer:
Remember, a homogeneous system always is consistent. Then we can reason with the rank of the matrix.
If the system Ax=0 has only the trivial solution that's mean that the echelon form of A hasn't free variables, therefore each column of the matrix has a pivot.
Since each column has a pivot then we can form the reduced echelon form of the A, and leave each pivot as 1 and the others components of the column will be zero. This means that the reduced echelon form of A is the identity matrix and so on A is row equivalent to identity matrix.

I know this is not an answer but, I love your handwriting!
It is soooo much neater than mine!
