See a solution process below:

Explanation:

The standard form of a linear equation is: color(red)(A)x + color(blue)(B)y = color(green)(C)

Where, if at all possible, color(red)(A), color(blue)(B), and color(green)(C)are integers, and A is non-negative, and, A, B, and C have no common factors other than 1

To transform this equation into Standard Form, subtract color(red)(7y) from each side of the equation to put the x and y variables on the left side of the equation as required by the Standard formula while keeping the equation balanced:

x - color(red)(7y) = 7y - color(red)(7y) + 2

x - 7y = 0 + 2

color(red)(1)x - color(blue)(7)y = color(green)(2)

color(red)(A = 1)

color(blue)(B = -7)

color(green)(C = 2)
