5x + 12 + 3x = 6(x + 4)
5x+3x+12=6(x+4)
Multiply the bracket by 6
(6)(x)(6)(+4)=6x+24
5x+3x+12=6x+24
8x+12=6x+24
Move 6x to the other side. Sign changes from +6x to -6x.
8x-6x+12=6x-6x+24
8x-6x+12=24
2x+12=24
Move 12 to the other side. Sign changes from +12 to -12.
2x+12-12=24-12
2x=12
Divide by 2 for both sides.
2x/2=12/2
x=6

Answer:
14
Step-by-step explanation:
-21+-13+20=14
This is true because when subtracting negatives by negatives you pretty much add them and then when you add a positive to a negative you are technically removing the negative by the amount you are adding.
In short its kind of like using inverse operation in a way.
Hope this helps and have a nice day
Also may I please have a brainliest!!!
Answer:
y = 4x-9
Step-by-step explanation:
16x-4y-36 = 0
-4y = -16x+36(subtract 16x from both sides and add 36)\
y = 4x-9(divide both sides by -4)
