Shown from explanation.

Step-by-step 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
