Question

4x + 5y = 7 3x – 2y = –12 Multiply each equation by a number that produces opposite coefficents for x or y

Answer 1

Answer:

Step-by-step explanation:

DO YOU MEAN :

$4x + 5y = 7\\ 3x - 2y = -12\\Multiply-equation 1 -by -the-coefficient-of-x-in-equation-2\\multiply-equation-2 -by-the-co-efficient -of x -in-equation- 1\\\\3(4x + 5y = 7)\\4( 3x - 2y = -12)\\\\12x +15y=21\\12x -8y=-48$
