See the entire solution process below:

Explanation:

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

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

First, subtract color(red)(12x)12x from each side of the equation to place both the xx and yy term on the left side of the equation as required by the standard form:

-color(red)(12x) + y = -color(red)(12x) + 12x12x+y=12x+12x

-12x + y = 012x+y=0

Because the xx coefficient must be positive we will multiply each side of the equation by color(red)(-1)1:

color(red)(-1)(-12x + y) = color(red)(-1) xx 01(12x+y)=1×0

(color(red)(-1) xx -12x) + (color(red)(-1) xx y) = 0(1×12x)+(1×y)=0

color(red)(12)x - color(blue)(1)y = color(green)(0)12x1y=0

color(red)(A = 12)A=12

color(blue)(B = -1)B=1

color(green)(C = 0)C=0
