Пошаговое объяснение:
2(3х-4)=4(х-3)
6x - 8 = 4x - 12
6x - 4x = -12 + 8
2x = -4
x = -4 : 2
x = -2
12-5(х+1)=+3х-2х
3(0,4у+3)-0,6у=8
1,2y + 9 - 0,6y = 8
0,6y + 9 = 8
0,6y = 8-9
0,6y = -1
y = -1 : 0,6
y = -1 2/3
2(3x-4)=4(x-3)
6x-8=4x-12
2x=4
x=2
12-5(x+1)=3x-2x
12-5x-5=x
7-5x=x
-5x-x = 7
-6x=7
x = -6/7
3(0,4y+3)-0,6y=8
1,2y+3-0,6y=8
0,6y=5
y= 30
