The work of a student to solve a set of equations is shown below:
Equation 1: m = 8 + 2n
Equation 2: 4m = 4 + 4n
Step 1: β4(m) = β4(8 + 2n)
4m = 4 + 4n
Step 2: β4m = β32 β 8n
4m = 4 + 4n
Step 3: β4m + 4m = β32 β 8n + 4n
Step 4: 0 = β32 β 4n
Step 5: n = β 8
In which step did the student first make an error?

Match each equation with the operation you can use to solve for the variable. subtract 10. divide by 10. divide by 5. subtract 18. multiply by 10. add 18. add 10. multiply by 5. 5 = 10p arrowright p + 10 = 18 arrowright p + 18 = 5 arrowright 5p = 10 arrowright
