(2). 4x-2x+8=2x-2x-10
(3). 2x+8=-10
(4). 2x+8-8=-10-8
(5). 6x=-2
(6). 6x/6=-2/6
(7). x=-1/3
Prove: x = 15
Answer:
see the procedure
Step-by-step explanation:
The picture of the question in the attached figure
we know that
----> by vertical angles
substitute the given values
solve for x
subtract 4 both sides
divide by 3 both sides
Answer:
the reason for 4 -> vertical angles theorem
3x + 4 = 49 is the answer for the other one
