Answer:
3x + 4y = -36
y = 2x - 9
3x + 4(2x - 9) = -36
3x + 8x - 36 = -36
11x - 36 = -36
11x = 0
x = 0
y = 2(0) - 9
y= 0-9
y = -9
(0, -9) is the answer

Answer: 
Answer:
3+4p+8t
Step-by-step explanation:
First step
5.(2x-8)
= (5.2x) + (5. (-8) )
=10x + (-45)
note :(+) . (-) = (-)
so + (-45)= (-45)
Add 15 to this equation
= 10x -40 +15= -15
=10x -25= -15
Leave x alone and make it positive
By the way, if you put (-25) in the right term, this number's notation (I mean -) will change
Namely
= 10x= (-15)+25
=10x= 10
x=1
Hope it helps :)
P.s. I dont know mathematical terms that's why i couldn't explain it properly but i tried to help as far as i can :)
