Question

1. Solve the inequality 8 + 6x 2 12 + 4x and show your work What value is a solution of 8 + 6x 2 12 + 4x but not a solution of 8 + 6x 2 12 + 4x?

Answer 1

Answer:

2, 8x - 8= 12 + 4x

The student did not distribute the 2 into the parentheses properly which ruined their entire problem. With 2(4x-4) , you must multiply everything in parentheses by 2.

so 2 x 4x = 8x

2 x -4 = -8

making it 8x- 8 = 12 + 4x ( on the right side all you did was combine like terms)
