Answer 2

Answer:

k = $\frac{9}{5}$

Step-by-step explanation:

given

5k + 1 = 10 ( subtract 1 from both sides )

5k = 9 (divide both sides by 5 )

$\frac{5}{5}$ k = $\frac{9}{5}$ , that is

k = $\frac{9}{5}$

ans (2) is incorrect

person has not divided through correctly by 5

Only divided 5 and 10 but not the 1
