Not sure if this is exactly what you want but an= a1 + (n - 1)d
Answer:
Step-by-step explanation:
You don't have any systems listed here, but it is any that you can use both of those ordered pairs for. Below is an example:
x + y = -1
x - y = 5
So angle 4 and angle 2 are gonna equal 180
So your equation should say
3x - 10 + 70 = 180
3x + 60 = 180
-60 -60
3x = 120
— —
3 3
X = 40
And your answers x = 40
Hope you understood
