The correct answer is that he needs to reverse the order of operations.
In the equation 8 + 3n = 20, the first operation to be performed is the addition of 8 and 3n. To isolate the variable n, Jonny needs to get rid of the 8 on the left side of the equation. The best way to do this is by subtracting 8 from both sides of the equation.
By subtracting 8 from both sides, Jonny can cancel out the 8 on the left side, leaving him with 3n = 12. This will allow him to solve for n by dividing both sides of the equation by 3.
Jonny is solving this equation for n : 8 + 3n = 20 . His first step is to subtract 8 from both sides of the equation. Why?
options:
8 is the first term in the equation.
He needs to reverse the order of operations.
He needs to follow the order of operations.
8 is attached to 3n by subtraction.
