Which equation has the solution n = 11?

3n + 12 = 45

Step-by-step explanation:

*Process of elimination*

3n + 12 = 45

(given)

3n + 12 = 45

- 12 - 12

(subtraction property of equality)

3n = 33

÷ 3 ÷ 3

(division property of equality)

n = 11

7n - 8 = 62

(given)

7n - 8 = 62

+ 8 + 8

(addition property of equality)

7n = 70

÷ 7 ÷ 7

(division property of equality)

n = 10 ≠ 11

8n + 6 = 102

(given)

8n + 6 = 102

- 6 - 6

(subtraction property of equality)

8n = 96

÷8 ÷8

(division property of equality)

n = 12 ≠ 11

5n - 20 = 25

(given)

5n - 20 = 25

+ 20 + 20

(addition property of equality)

5n = 45

÷5 ÷5

(division property of equality)

n = 9 ≠ 11

it's 3n+12=45

Step-by-step explanation:

3n+12-12=45-12

3n=33

=11

step-by-step explanation:

1. practice, practice & more practice
