Question

How do you solve 10n+20n+147=1,167?

Answer 1

Hey there!

Answer:

n = 34.

Step-by-step explanation:

10n + 20n + 147 = 1167

30n = 1167 - 147

30n = 1020

n = 1020 / 30

n = 34

Answer 2

Answer : n = 34

Step by step explanation :

$10n + 20n + 147 = 1167$

Collect the like terms by adding their coefficients and then add the numbers.

$= > 30n + 147 = 1167$

Move constant to the right by adding its opposite to both sides

$= > 30n + 147 - 147 = 1167 - 147$

Eliminate the opposites

$= > 30n = 1167 - 147$

Subtract the numbers

$= > 30n = 1020$

Divide both sides of the equation by 30

$= > 30n \div 30 = 1020 \div 30$

Any expression divided by itself equals 1

$= > n = 1020 \div 30$

Calculate the quotient

$= > n = 34$
