Equation Given:3(n-5)=21

Step-by-step explanation:Step 1:step 2:step 3:step 4:step 5:Step6:Vertifying:→3(n-5)=21→3(12–5)=21→3×7=21→21=21★Hencevertified★Answer:n = 12

Step-by-step explanation:We are given,

3(n – 5) = 21

(n – 5) = 21/3

n – 5 = 7

n = 7 + 5

n = 12

OR

3(n – 5) = 21

3n – 15 = 21

3n = 21 + 15

3n = 36

n = 36/3

n = 12

Hence, n = 12

Hope it helped and you understood it……..All the best
