Kisha and Rae are asked to solve –5x – 14 = 2x + 7. Identify where one of them made an error.
Kisha
Rae
–5x – 14 = 2x + 7
–5x – 14 – 2x = 2x + 7 – 2x
–7x – 14 = 7
–7x – 14 + 14 = 7 + 14
–7x = 21
Negative 7x over negative 7 equals 21 over negative 7
x = – 3
–5x – 14 = 2x + 7
–5x – 14 + 5x = 2x + 7 + 5x
–14 = 7x + 7
–14 + 7 = 7x + 7 + 7
–7 = 7x
x = – 1
(1 point)
Rae made the error when she added 7
Rae made the error when she added 5x
Kisha made the error when she subtracted 2x
Kisha made the error when she divided by –7
