If a is equal to the sum of band c, what is the difference of band c?
The difference of b and c is equal to
... in terms of b and a.
... in terms of c and a.
To find the difference of b and c in terms of b and a, you can start by recalling that a is equal to the sum of b and c. This can be written as:
a = b + c
Now, let's solve this equation for c. We can do this by subtracting b from both sides of the equation:
a - b = b + c - b
Simplifying the right side, we get:
a - b = c
Therefore, the difference of b and c in terms of b and a is given by (a - b).
To find the difference of b and c in terms of c and a, we can rearrange the equation a = b + c to solve for b. Here's how:
a = b + c
Subtracting c from both sides of the equation:
a - c = (b + c) - c
Simplifying the right side, we get:
a - c = b
Therefore, the difference of b and c in terms of c and a is given by (a - c).
a = b + c
subtracting 2c ... a - 2c = b - c
subtracting 2b ... a - 2b = c - b
