We have been given the steps to solve the equation as
Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
There is an error in step 2.
We have
x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.
So we must divide both sides by 2.
Therefore, A is the correct option.
A) She did not divide 18 by 2.
Answer:
4 years
Step-by-step explanation:
I = $ 400
R = 5%
P =$ 2000
I = Prt
400 = 2000 * * t
400 = 20 * 5 * t
400 = 100 t
t = 4 years
