D.
6.50x=1.30

Answer 1

A student solved an equation, as shown below.
The first line shows 1 over 4 left Parenthesis 8 minus 12x right parenthesis equals x minus 2 left parenthesis 2x plus 1 right parenthesis, second line shows 2 minus 3x equals x minus 4x plus 2, third line shows 2 minus 3x equals 3x plus 2, fourth line shows 2 minus 3x plus 3x equals negative 3x plus 3x plus 2. Fifth line shows 2 equals 2.

Answer 3

are you sure

Answer 4

A. 1.30x = 6.50 is the correct equation to solve the problem.

Answer 5

The student solved the equation correctly because the original equation has equivalent expressions on both sides of the equation.

Answer 6

This problem has no solutions.

Answer 7

I apologize for the earlier incorrect response. Let's analyze the equations again. Based on the given equations:

1/4(8-12x) = (x-2)(2x+1)
2-3x = x-4x+2
2-3x = 3x+2
2-3x+3x = -3x+3x+2
2 = 2

From the calculations, we can see that the equation simplifies to 2 = 2. Therefore, the equation is true for all values of x. Hence, there are infinitely many solutions to this problem.
