Answer:
x = 21
Step-by-step explanation:
-7 ( x + 1 ) - 3 = -8x + 11
-7x - 7 - 3 = -8x + 11
x = 7 + 3 + 11
x = 21
B=5
You need to get b by itself on the left side. 4b is multiplying 4 to b. You need to the opposite when you want the variable by itself. You would divide 4 to each side. 4 cancels out on the b so it turns into b. Then 4 divided by 20 is 5. B=5

Answer:
No
Step-by-step explanation:
The angles of a triangle must always add up to 180 degrees.
90 + 60 + 60 = 210 degrees.
Therefore it would not be possible to draw a triangle with these values.
