In what step is there first an error. Please explain the error, what misunderstandings the student has and how to correctly work the problem.
Given: 2(10 −13) +9 = −34 + 60
Step 1: 20 − 26 + 9 = −34 +60
Step 2: 17 = −34 +40
Step 3: 51x = 40
Step 4: =
40
51

step 2 is their first error

Step-by-step explanation:

they made the wrong calculations.

all that's left to do is to add -34 and 60

they solved the left side of the equation and randomly subtracted 20 from the 60 and moved it to the left side. It was supposed to be -17. Then they moved -34 to the left side of the equation and added an x out of nowhere.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
