Ax 2y 6 9x 3y 12 ekvationssystem
WebSo lets recap, we add or subtract a variable to cancel out the other variable in elimination. If 4x-2y=14 was actually 4x+2y=14, and do what we did, it wouldn't cancel out the first equation. To get it to cancel out 2y, we multiply the equation by (-1) by both sides. -1 (4x + 2y) = (14)-1.

WebAhora, la otra ecuación es... la voy a poner aquí en naranja, "9x" más "3y" es igual a 15. Cuando despejamos "y" de la segunda ecuación, encontramos que "y" es igual a 5 más "x", así es que podemos sustituir "y" de la segunda ecuación con 5 más "x", de esa manera garantizamos que estamos cumpliendo con ambas restricciones, hagamos eso ... WebAug 6, 2015 · f (x) = mx + b. Note: m is the slope of the line; b is the y-intercept (the value of y when x=0) Starting with 9x+3y=12. you should first divide all terms by 3, because 3x + y = 4 is precisely the same line. Then, solve for y= f (x) = -3x + 4 (by subtracting 3x from both sides) This is the slope-intercept form of the line.
