Answer:
x = 28
Step-by-step explanation:
The 2 angles must add up to 180°, as definition of a line.
4x + 7 + 2x + 5 = 180
6x + 12 = 180
6x = 168
x = 28
Answer:
n= -3.5
Step-by-step explanation:
n/7 - 12 = 5n +5
+12 +12
n/7 = 5n+17
*7 *7
n = (5n+17)*7
n = 35n + 119
-35n -35n
-34n = 119
/-34 /-34
n = -3.5
