Answer:
20
Step-by-step explanation:
3x+50 = 6x-10( opposite angles are equal)
3x = 60
x = 20
From the equation, we can tell that left side of the equation has to be less than or equal to 6 in order for the equation to be true.
So first, let’s try n=0.
Plug it in: 2(0)=0 and since 0 is less than 6, it makes the equation true.
Next, let’s try 1. 2(1)=2. This also makes the equation true.
Next, let’s do n=3. 2(3)=6. So this also makes the equation true.
So the answers are:
n=0 , n=1 , and n=3

For #6, x=-3, add 4 to both sides, divide by 2. #7 is 8, #8 is 3, #9 is 3, #10 is -5.
