Plug y= -3x in 2x-3y= 22, we have:
2x -3(-3x)= 22
⇒ 2x+ 9x= 22
⇒ 11x= 22
⇒ x= 22/11
⇒ x= 2
y= -3x= -3*2= -6
Final answer: x=2, y=-6~

Answer:what’s the question?
Step-by-step explanation:
Answer:
a) 3c
b) ab
c) -ab
Step-by-step explanation:
For x > 0, |x| = x. This lets us remove the absolute value symbols in parts (a) and (b):
a. |3c| = 3c . . . when c > 0
b. |ab| = ab . . . when ab > 0
c. The absolute value function returns the opposite of its argument when that argument is negative:
|ab| = -ab . . . when ab < 0
