Answer:
a-b = 2a
a-b = -2b
Step-by-step explanation:
a+b = 0
Subtract b from each side
a+b - b=0-b
a = -b
a-b =
Replace a with -b
-b -b= -2b
a = -b
Divide by -1
-a =b
or replace b with -a
a - (-a)
a+a
2a
Answer:
Synthesis or replication of DNA
Step-by-step explanation:
You can remember that because synthesis starts with an S
So you have the equation (2x+4)/-3=12
Multiply by -3 on each side.
2x+4=-36
2x=-20
x=-10
Hope this helps.
12 would be right since 3-12 would be 9 then 9 times 2 is 18.
