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.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
