помогите решить уравнения 3,2x+4,8=-2*(1,2x+2,4) -5*(0,8x-1,2)=x+7,2
3,2x+4,8=-2*(1,2x+2,4)
5.6x+4.8+4.8=0
5.6x+9.6=0
x=-9.6/5.6 x=-12/7 x=-1 5/7 -5*(0,8x-1,2)=x+7,2
-4x+6-x-7.2=0
-5x+6-7.2=0
-5x-1.2=0
x=-1.2/5 x=-0.24
3.2x+4.8 =-2(1.2x+2.4)
3.2x+2.4x = -9.6
5.6x = -9.6
x=-9.6/5.6
x=-2.4/ 1.4
x=-1.2/0.7
-4x+6 = x+7.2
5x=-1.2
x=-1.2/5
x=-0.24
