Liliana solved the equation below. When she tried to verify her answer, she realized she made an error. One-third (x 18) = 7 One-third x 6 = 7 One-third x 6 minus 6 = 7 6 One-third x = 1 x = 3 Which correction should Liliana make? The first step should be One-third x 54 = 7. The second step should be One-third x 6 minus 6 = 7 minus 6. The third step should be One-third x = 13. The final step should be x = one-third.
