Answer:
your answer for the question would be A I dont Know about part be
For the first problem you will add 4 to both sides so that n is alone ex:
n-4=-2
+4. +4
————-
n=2
So the answer would be “add 4 to both sides”
And for the second question would be to add 4K to both sides I believe
Answer:
To answer this question you need to x and y
Step-by-step explanation:
Answer: the number is -3
Step-by-step explanation:
Four times a number is three times the difference of that number and one
Let the number be x. Four times the number means 4×x = 4x
three times the difference of that number and one. This means
Difference of the number and one is (x-1). Three times the difference of the number and one would be 3(x-)
Four times a number = three times the difference of that number and one. Therefore,
4x = 3(x-1)
Opening the bracket
4x = 3x -3
4x-3x = -3
x =-3
Check
4×-3 =3(-3-1)
-12 = -3×4
-12 = -12
So the number is -3
