Well formatted version of question :
Olga tried to solve an equation step by step
1/4(1/3k+9)=6
step 1- 1/3k+9=24
step 2- 1/3k=15
step 3- k=5
find olgas mistake
step 1
step 2
step 3
olga did not make a mistake
Step 3
Step-by-step explanation:
Given the equation :
1/4(1/3k+9)=6
Step 1 : Olga multiplied both sides by 4
1/4(1/3k + 9) * 4 = 6* 4
1/3k + 9 = 24
Step 2 : Olga subtracted 9 from sides
1/3k + 9 - 9 = 24 - 9
1/3k = 15
Step 3 : Both sides should be multiplied by 3
1/3k * 3 = 15 * 3
k = 45
This is the step Olga made a mistake. Olga attempted to divide 15/3 = 5 instead of Multiplying 15 * 3 to obtain 45
