Answer:

1. x = 10

2. n = 3

Step-by-step explanation:

1.) 50 = 2x + 30

Subtracting 30 from both sides, we get:

50 - 30 = 2x

20 = 2x

Dividing both sides by 2, we get:

x = 10

Therefore, the solution is x = 10.

2.) 11 = 6n - 7

Adding 7 to both sides, we get:

11 + 7 = 6n

18 = 6n

Dividing both sides by 6, we get:

n = 3

Therefore, the solution is n = 3.
