Answer:
(3/5)x+1/4=(3/4)x-2/5
<=> (3/5)x - (3/4)x= -2/5 - 1/4
<=> x(12/20 - 15/20) = -13/20
<=> x(-3/20) = -13/20
<=> x = 13/3

Answer:
Hi there
Adjacent angles are two angles that have a common side and a common vertex (corner point), and don't overlap. Vertical angles are the angles opposite each other when two lines cross
Answer:
The first one, the third one, and the fourth one.
Step-by-step explanation:
i just put the ones that are correct. If you want me to write out why the incorrect ones are incorrect, let me know.
1.
-6=3x
-6= 3(-2)
-6= -6
3. -8= x+x+x+x
-8= -2+-2+-2+-2
-8= -8
4. x/2= (-1)
-2/2 =(-1)
-1= -1
