Let us solve this system of equations by using the elimination method. Adding the 2 equations, we get

9x + 5y - 9x + 4y = -33 + 6

9y = -27

y = -3

Substituting this value of y in the first equation, we get

-9x + 4(-3) = 6

-9x - 12 = 6

9x + 12 = -6

9x = -18

x = -2

Therefore, x = -2, and y = -3. Hope this helps! If you have any questions, feel free to ask.

Evaluate 7(-4) - |-6| + |4| A. 13 B.-18 C. -30

tester [92]

Hello there!

Answer: ⇒ C. -30

_________________________________________________________

Step-by-step explanation:

First you had to remove parenthesis.

$-7*4-|-6|+|4|$

Then you multiply by the number.

$=-28-|-6|+|4|$

Apply absolute value.

$|-6|=6$

$=-28-6+|4|$

Again apply absolute value.

$|4|=4$

$=-28-6+4$

Simplify it's should be the correct answer.

$=-30$
