Answer:
3, 50, 2
Step-by-step explanation:
By multiplying all terms by 5, we are trying to remove the fraction on the left hand side. On the right hand side of the equation, expand the bracket by multiplying 5 to each term in the bracket.
3(n +25)= 5(10) +5(
)
3(n +25)= 50 +2n
To find the value of n, expand the bracket on the left hand side:
3(n) +3(25)= 50 +2n
3n +75= 50 +2n
Bring all n terms to one side, constants to the other:
3n -2n= 50 -75
n= -25
Number one is x=9,-9
number two is x=0
number three is x=12,-12
number four is 5i, -5i
Answer:
There isn't much to say. Since the x repeats, and the y's are different, it wouldn't be a function.
Answer:
(7 , - 0.5)
Step-by-step explanation:
(8 , -6) ; (6, 5)

13 ( 19 - x)
Distribute 13 into the parenthesis.
13 (19) 13 (-x)
= 247 - 13x
They aren't like terms so we leave the answer as: 247 - 13x
