2(n-1)+ 4n= 2 (3n -1)

Mathematics
1 answer:
muminat3 years ago

Answer:

Infinitely many solutions.

Step-by-step explanation:

2 (n - 1) + 4n = 2 (3n - 1) Let's simplify this to solve it.

2n - 2 + 4n = 6n - 2 Distribute 2(n-1) and 2(3n-1)

2n + 4n - 2 = 6n - 2 Rearrange the left side of the equation.

6n - 2 = 6n - 2 Add 2n + 4n.

-6n        -6n Subtract 6n from both sides.

-2 = -2

the answer is infinitely many solutions, meaning that n can be any real number.

Anna is saving to buy some souvenirs on a family vacation. She has already saved $125, and she saves another $2 from her
FinnZ [79.3K]

We can assume that the y-intercept for this equation is 125, because that would be how much Anna already has saved before she begins saving money from her allowance. Then, we know that Anna adds $2 to her savings each day from the problem, so we know that the slope will be positive 2 then.

Equation:

y = 2x + 125

Graph:

Hope this helps!! :)

The sum of 1/3 and twice a number is equal to 2/3 subtracted from three the number.find the number
Zigmanuir [339]
The number = y

2y + 1/3 = 2/3 - 3y
(add 3y to both sides)
5y + 1/3 = 2/3
(subtract 1/3 from both sides to isolate y)
5y = 1/3
(divide by 5)
y = 1/15
