Answer
Step-by-step explanation:
12 divided by 4=3
18-3+5-3
5 minus 3 = 2
18-3+2
18 minus 3 = 15
15+2= 17
answer is 17
Answer:
13b-12a+5 (so the last one)
Step-by-step explanation:
b-6a+12b-6a+5
13b-12a+5
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.
No.
2+4 is not greater than 8.
For one set the two equations equal to eachother and solve from there. 2 is 45
For three set the two equations equal. Same for four
