Commutative law: a+b=b+a thats it...
So 9+7 can also be written as 7+9=16
2a(b+3+4bc)
just take out the greatest common factor :)
Answer
x=-12

-2x=24
Divide both sides of the equation by -2
x=-12
Hope this helps:)

Answer:
x=4.5
Step-by-step explanation:
Using sohcahtoa we know tangent is equal to (length of side opposite to the angle ) / (lenth of side adjacent to the angle)
therefore: tan (theta) = (x-3) / (x) = 1 / 3
now cross multiply
3(x-3) = x
now solve for x
3x - 9 = x
-9= -2x
x= 4.5
