x+3y=9

OpenStudy (anonymous):

Solve for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3y' to each side of the equation. x + 3y + -3y = 9 + -3y Combine like terms: 3y + -3y = 0 x + 0 = 9 + -3y x = 9 + -3y Simplify x = 9 + -3y

to solve for y, move the x over so the equation is 3y=-x+9 then divide both sides by 3 so that y=-1/3x+3, which is also that equation in slope intercept form
