Answer:
3 = x
Step-by-step explanation:
0 > 3x - 3 - 6
You want to group up the -3 and -6 first
0 > 3x - 9
Then you want to add 9 to each side to cancel out the negative 9 on one side.
0 > 3x - 9
+9 +9
9 > 3x
Now you just divide by 3 on each side
3 = x
Answer:

shows the commutative property of addition
Answer:
m∠A = 9°
Step-by-step explanation:
Answer:
x=0,-2
Step-by-step explanation:
Solve the solution by equaling them to each other and solve for x.
x^2+5x+6=3x+6
x^2+5x-3x+6-6=0
x^2+2x=0 (factor out one x)
x(x+2)=0
x has two solutions since there are two options of solving.
1. x=0/(x+2)
x=0
2. x+2=0/x
x+2=0
x=-2
