Marcie solved the following inequality and her work is shown below:. . −2(x − 5) − 12 ≤ 4 + 6(x + 3). −2x + 10 − 12 ≤ 4 + 6x + 18. −2x − 2 ≤ 6x + 22. −8x ≤

Marcie solved the following inequality and her work is shown below:. . −2(x − 5) − 12 ≤ 4 + 6(x + 3). −2x + 10 − 12 ≤ 4 + 6x + 18. −2x − 2 ≤ 6x + 22. −8x ≤ 24. x ≤ −3. . Wh
The mistake which Marcie made in solving the equation was when she added 2 to 6x and 2 to 22 to make ≤ 24. x ≤ −3.Adding 2 to 6x would make 6x + 2, therefore this is the mistake that Marcie made solving the inequality. ...
