Question

Which of the following options is the standard form of the linear equation 7x - 21 + 2y = 0?

7x + 2y - 21 = 0
21 + 2y + 7x = 0
2y + 7x - 21 = 0
7x - 21 + 2y = 0

Answer 1

The standard form of the linear equation 7x - 21 + 2y = 0 is 7x + 2y - 21 = 0.

Step-by-step explanation:

The standard form of a linear equation is in the form ax + by + c = 0, where a, b, and c are constants. In the given equation, 7x - 21 + 2y = 0, we can rewrite it in the form ax + by + c = 0 by rearranging the terms. So, the correct standard form of the equation is 7x + 2y - 21 = 0.
