There are 15 biography books and there are 48 books in total so the ratio is 15:48
F(x)=2x-5
Insert the value of x which is x+1 ->
F(x+1)= 2(x+1)-5
Distribute ->
F(x+1)=2x+2-5
Then, add like terms->
F(x+1)=2x-3
Answer:
x=7/2
Step-by-step explanation:
11=4x−3
Step 1: Flip the equation.
4x−3=11
Step 2: Add 3 to both sides.
4x−3+3=11+3
4x=14
Step 3: Divide both sides by 4.
4x
