what would we do to both sides to solve this equation for n: n + 1.2 = 6.4
(a) Subtract 6.4 from both sides
(b) Subtract 1.2 from both sides
(c) Add 1.2 to both sides
To solve the equation for n, we need to isolate n on one side of the equation.
In this case, we can achieve this by subtracting 1.2 from both sides.
So the correct option is:
(b) Subtract 1.2 from both sides: n + 1.2 - 1.2 = 6.4 - 1.2
This simplifies to: n = 5.2.
