Multiply the first bracket by -2
Multiply the second bracket by 2
x-3-12+4x= 4x-10
- negative number times + positive number= - negative number
- negative number times -negative number = + positive number
x+ 4x-3-12= 4x-10
5x-15= 4x-10
Move 4x to the other side
5x-4x-15= 4x-4x-10
x-15= -10
Move -15 to the other side
x-15+15= -10+15
x= 5
Answer : x= 5

Answer:
Option A is the correct choice.
Step-by-step explanation:
Let us see the given steps of Janice's solution to find error made by her.
1.

We have been given that
pounds of meat was used and each batch required
pounds of meat, therefore, 1st step is correct.
2.
Upon converting our mixed fractions to improper fractions we will get,
We can see that Janice converted
to
, which is not correct. Janice wrote 2 in the denominator of second mixed fraction instead of 3.
Janice converted a mixed number to the wrong improper fraction, therefore, option A is the correct choice.
