3n+1=19 so i'm learning to solve 2 step equations in pre algebra but i don't really understand.

n = 6

Step-by-step explanation:

Simplifying

3n + 1 = 19

Reorder the terms:

1 + 3n = 19

Solving

1 + 3n = 19

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-1' to each side of the equation.

1 + -1 + 3n = 19 + -1

Combine like terms: 1 + -1 = 0

0 + 3n = 19 + -1

3n = 19 + -1

Combine like terms: 19 + -1 = 18

3n = 18

Divide each side by '3'.

n = 6

Simplifying

n = 6

n = 6

Step-by-step explanation:

3n + 1 = 19

Subtracting 1 from both sides:

3n + 1 - 1 = 19 - 1

3n = 18

Dividing both sides by 3:

3n/3 = 18/3

Simplifying:

18/3 = 6

n = 6

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
