when you multiply two minus numbers the minus signs cancel each other out so -12 * -6 = 72

We'll go ahead and find the answer, even though we're not completely convincedthat you know what the question is.-12x = 72Divide each side of the equation by -12:x = -6
2x - 3y = -1 Eq.1y = -4x + 24 Eq.2Put the value of Eq.2 on Eq.22x - 3(-4x + 24 ) = -12x + 12x -72 = -114x -72 = -114x = 72-114x = 71x= 71/14 .............. X = 5.07
Without an equality sign it is not a straight line equation but if you mean 9y-12x-72 = 0 then y = 4/3x+8
3x+27=12x-45 Bring x to one side and the numbers to the other 45+27=12x-3x 72=9x x=8 For any step you don't understand message me
Plug in zero for x and solve the equation to get 72. In other words, the line created by this equation crosses the y axis at 72 when the value of the x axis is zero. In the general form y = mx + b, b will always be the y intercept.
