Answer:

(7, 1/2)

Step-by-step explanation:

Multiply second equation by 2 and subtract.

3x - 4y = 19

- (4x - 4y = 26)

You get -x = -7

x = 7

Substitute x into any equation.

3(7) - 4y = 19

21 - 4y = 19

-4y = -2

y = 1/2

Intentionally writing a check on an account with insufficient funds should not be done. True Fals

Ede4ka [16]

False.

The above statement is false because for intentionally writing a check on an account with sufficient funds, it is only considered illegal when it is intended for check kiting, it is written above $100 and has been done more than once.

If it has been done for the 1st time with the intent of depositing an amount to cover the issued check, then it would not be illegal.
