Question

3x-x=y-4 x+1/3=y+2/2+×/6??

Answer 1

3x-x=y-4
x+1/3=y+2/2+×/6

2x - y = -4

x -x/6 -y = 2/2 -1/3
MMC de 1 e 2 e 3 e 6 = 6
6x/6 - x/6 -6y/6 = 6/6 - 2/6
6x-x-6y=6-2
5x-6y=4

2x-y=-4
5x-6y=4

x = -4/2 + y/2
5 *( -4/2 + y/2) - 6y = 4
-20/2 + 5y/2 -6y = 4
-10 + 2,5y - 6y = 4
-3,5y = 4 + 10
-3,5y = 14
y=14/(-3,5)
y= - 4

x = -4/2 + y/2
x= -2 + (-4)/2
x=-2 - 4/2
x= -2 - 2
x= -4
