You can combine the same numbers with the same variables using the operation sign for each. For example, using your equation, you would combine the 3n and 4n which is 7n. So your equation would be
7n - 2

Answer:
32
Step-by-step explanation:
Remark
Every triangle has 180 degrees as the total of its 3 angles.
Equation
x + 98 + 50 = 180
Solution
Combine the like terms on the left
x + 148 = 180
Subtract 148 fro both sides of the equation
x + 148- 148= 180 - 148
Combine
x = 32
x is 32 degrees in size
Answer:
20 points
Step-by-step explanation:
Points:
- 21, 13, 14 and x for the last game
Average:
- (21+13+14+x) / 4 = 17
- 48 + x = 4*17
- 48 + x = 68
- x = 68 - 48
- x = 20
They must score 20 points
