Question

The work of a student to solve a set of equations is shown below:

Equation 1: m = 6 + n
Equation 2: 2m = 8 + 8n

Step 1: –2(m) = –2(6 + n)
2m = 8 + 8n

Step 2: –2m = –12 – 2n
2m = 8 + 8n

Step 3: –12 – 2n = 8 + 8n

Step 4: –20 = 10n

Step 5: n = –2


In which step did the student first make an error? (4 points)

Answer 9

A student is trying to solve the system of two equations given below:

Equation P: x + y = 8
Equation Q: 2x + 5y = 24

Which of the following steps can be used to eliminate the x term? (4 points)
