8 is attached to 3n by subtraction.
Jonny is subtracting 8 from both sides of the equation to isolate the variable term, 3n, on one side. This is done to solve for n.
The correct answer is: He needs to reverse the order of operations.
In order to solve the equation 8 + 3n = 20, Jonny needs to isolate the variable n on one side of the equation. The equation currently has the variable n combined with 8 through addition.
To separate the term 8 from the equation, Jonny needs to perform the opposite operation, which is subtraction. By subtracting 8 from both sides of the equation, the term 8 on the left side will cancel out, leaving only the term 3n on the left side, which is what Jonny wants to isolate.
So, in conclusion, Jonny subtracts 8 from both sides of the equation to reverse the operation and isolate the variable n.
The correct answer is: 8 is the first term in the equation.
When solving an equation, it is often helpful to isolate the variable on one side of the equation. In this case, since 8 is the first term in the equation, subtracting 8 from both sides will help Jonny isolate the variable (n) on one side of the equation.
