Question

I know this is difficult but please. ill give 60 points

Sally is solving the linear equation 13 + 4x - 9 = 7x + 7 -3x. Her final two steps are: 4 + 4x = 4x + 7
4 = 7
Select statement that correctly interprets Sally's solution.
A. The solution is x = 0
B. The solution is the ordered pair (4, 7)
C. There is no solution since 4=7 is a false statement.
D. There are infinitely many solutions since 4 = 7 is a false statement

Answer 1

The answer is C. There is no solution since 4 = 7 is a false statement.

Explanation:

The given problem is 13 + 4x - 9 = 7x + 7 - 3x.

The simplified version of it is 4 + 4x = 4x + 7.

Taking away the 4x on either side will leave you with 4 = 7.

Therefore, the answer is C. There is no solution since 4 = 7 is a false statement.

Answer 2

C

Explanation:

Sally's solution

4 + 4x = 4x +7

4 = 7

since 4 does not equal 7 this answer is false therefore, C is the correct answer
