Answer:
1= X
Step-by-step explanation:
Start with PEMDAS
3 x 4 is 12
3x -X is -3X
-3 x 2 is -6
-3 x -X is 3 X NEGITIVE X NEGATIVE = +
so now you got
12 - -3X -6 +3X
again - × - = +
so know you got 12 + 3X -6 +3X
Additions is next in PEMDAS
so 12 -6 is 6 and 3X + 3X is 6X
so 6X =6 so Divide by 6 and you get 1 =X
Answer:
f(x)+ g(x) =
Step-by-step explanation:
You just have to add the like terms separately,
5-7 in 
only 6 in 
10-2 in
-8 in x
and 3 as the constant
m∠L = 5x - 28
m∠N = 3x - 10
m∠L ≡ m∠N
5x - 28 = 3x - 10
- 3x - 3x
2x - 28 = -10
+ 28 + 28
2x = 18
2 2
x = 9
m∠L = 5x - 28
m∠L = 5(9) - 28
m∠L = 45 - 28
m∠L = 17
m∠N = 3x - 10
m∠N = 3(9) - 10
m∠N = 27 - 10
m∠N = 17
x + 17 = 180
- 17 - 17
x = 163
m∠O = 163
