1. решите уравнение. а) -4,8x + 8 = 1,6x - 11,2 б) 2(0,6x - 3) = 3(-0,1x + 3)

а) -4,8x + 8 = 1,6x - 11,2
-4,8х-1,6х=-11,2-8
-6,4х=-19,2
х=-19,2:(-6,4)
х=3
б) 2(0,6x - 3) = 3(-0,1x + 3)
1,2х-6=-0,3х+9
1,2х+0,3х=9+6
1,5х=15
х=15:1,5
х=10

A) -4.8x+8 = 1.6x - 11.2
-4.8x-1.6x = -11.2-8
-6.4x = -19.2
x= 3

б) 2(0.6x-3)= 3(-0.1x+3)
1.2x-6 = -0.3x+9
1.2x+0.3x = 9 +6
1.5x = 15
x=10
