The equation you gave (-9x - 36 = 6x) does not have y included anywhere. Assuming you meant that -9x - 36 = 6x + y: Step 1: Give y its own side: -9x - 36 -6x = 6x - 6x + y -15x -36 = y Step 2: Set x as 0 -15(0) - 36 = y y = -36 The y-intercept is -36
36
Try system.X + Y = 62X - Y = 36X + Y = 62- (X - Y = 36)X + Y = 62- X + Y = - 36------------------------------add2Y = 26Y = 13==============The numbers.
y2 - 36 does not have a value unless we know what y is. We can, however, factor this expression: it factors to (y + 6)(y - 6).
