Question

Which line shows the first error in the solution?

Four less than a number divided by 6 is –16. What is the number?

x/6 - 4 = -16 (1)
x/6 - 4 + 4 = -16 (2)
x/6 = - 16 (3)
x/6 x 6 = -16 x 6 (4)
x = -96 (5)

2nd Question

Which line shows the first error in the solution?

4x + 8 = 2x - 10 (1)
4x - 2x +8 = 2x - 2x - 10 (2)
2x + 8 = -10 (3)
2x + 8 - 8 = -10 - 8 (4)
6x = -2 (5)
6x/6 = -2/6 (6)
