The reason Onny subtracts 8 from both sides of the equation is that he wants to isolate the variable term, which in this case is 3n. By subtracting 8 from both sides, he is eliminating the constant term on one side of the equation, making it easier to solve for n.
so whats the answer
To solve the equation 8 + 3n = 20, Onny subtracts 8 from both sides:
8 + 3n - 8 = 20 - 8
3n = 12
Now, to find the value of n, divide both sides of the equation by 3:
3n/3 = 12/3
n = 4
So, the solution to the equation is n = 4.
8 + 3n - 8 = 20 - 8
3n = 12
Now, to find the value of n, divide both sides of the equation by 3:
3n/3 = 12/3
n = 4
So, the solution to the equation is n = 4.
