Question

An equation and the steps to solve it are shown below:

Answer 1

Hello,

2x - one over four of (12x + 4) = 3
must be written:
2x-1/4 *(12x+4)=3
And we see a sign '-' before 1/4.

Step 1:
2x-(3x+1)=3 or 2x-3x-1=3 and not 2x+3x-1=3

Answer A
since  Step 1, because incorrect signs have been used








And here, Mehek are there sufficients explanations?

Answer 2

2x - one over four of (12x + 4) = 3 in the original statement is expressed as 2x - 0.25 *(12x +4). The "of" conjunction means multiplication. Therefore,the statement is expressed as 2x - 3x -1 = 3. Step one shows different signs on the third and second terms as it did not consider the negative sign. The answer hence is A. Step 1, because incorrect signs have been used
