Question

a + b = cd, solve for a

Answer 1

Since we don't have values for b, c, and d, we can't get a specific number for the value of a, if that makes sense. It'll be represented by these variables.

To solve, we need to make sure the equation looks like a = ? .

Subtract b from each side of the equation.

a = cd - b

Now we have solved for a.

Answer 2

cd-b=a is the answer for a in this case ok
