Solve the formula Ax + By = C for x.

X = (C-by)/A

Step-by-step explanation:

Ax + By = C

Ax = C - By

X = (C-by)/A

The numbers are best written as, 
                         (1.2 x 10⁻²)(3.65 x 10⁸)
If we multiply the bases of the scientific notations, we get an answer of 4.38. There exists a rule which states that for exponents of the same number which are multiplied, we add up the exponents. Thus, our final answer would be,
                               4.38 x 10⁶
