Answer:

Shown from explanation.

Explanation:

Let's compute the solution for the individual cases:

For Cullen;

Wrong Step:

Collecting and summing the like terms of n should result to -2n not -10n.

Solution;

-6n +22 = -4n + 14

Collecting like terms of n

-6n +4n= 14 -22

-2n = -8

n = -8/-2 = 4

For SERAPHINA:

Wrong Step:

The division y= 23.2/11.6 is wrong it should be 2.

Hence the right solution is;

y= 23.2/11.6

y= 2

For JASPER:

Wrong step:

Evaluating b from;

1/8b = 64

b = 8 is wrong.

Correction:

From 1/8b = 64

Multiplying both sides by 8 we have:

1/8 b × 8 = 64 × 8

b = 512

Answer:

Cullen: When adding 4n to both sides, Cullen subtracted instead.

Correct: -2n+22=14, -2n=-8, n=4

Seraphina: When dividing by 11.6, Seraphina subtracted 11.6.

Correct: y=2

Jasper: When subtracting 3/4, Jasper should have got -1/8, but got 1/8 instead. Also, he made another mistake where he said that 1/8b=64, and then said b=8.

Correct: -1/8b-32=32, -1/8b=64, b=-512
