Hope this helpssss :)
Answer:
'16' is the answer.
Step-by-step explanation:
So, 6=x+2 divided by 3. In this case, we can multiply 6 and 3 which makes
18 = x+2. We substract 2 from 18 and the answer is 16. If you don't understand anything, you can ask by leaving a comment below. Thanks.
16+2 = 18/3 = 6
/ symbol is used for division.
/ is same as ÷
Sometimes, fractions are shown as ratio, in which case, : symbol is used.
We can write the fraction
as 1/2 or 1÷2 or 1:2
Apply substitution
x+4(-2x-4)=19
x – 8x – 16 = 19
-7x = 19 + 16
-7x = 35
x = -5
Then substitute this value to the other equation
y=-2x-4
y = -2(-5) – 4
y = 10 – 4
y = 6
the answer is then letter A. (-5,6)
