Answer: i only know question one so here
The first mathematical error occurred going from line __3__ to line _4___.
Why it is incorrect:
It is incorrect because the minus sign was not properly distributed. Line 4 should be ...
5 -2x +6 ≤ 4x -8
a.
The second mathematical error occurred going from line ___5_ to line 6____.
Why it is incorrect:
It is incorrect because 1 was added on the left and subtracted on the right. The same number needs to be added or subtracted on both sides.
b. Solve the inequality correctly.
5 -2x +6 ≤ 4x -8---------------correct line 4
11 -2x ≤ 4x -8------------ combine constants
19 -2x ≤ 4x ------------add 8
19 ≤ 6x--------------- add 2x
19/6 ≤ x----------- divide by 6
