Question

СРОЧНО!!!!! Пожалуйста!!!!

Answer 1

6x-19=-2x-15
6x+2x=-15+19
8x=4
x=4:8
x=1/2=0,5

0,2x+3,4=0,6x-2,6
0,2x-0,6x=-2,6-3,4
-0,4x=-6
x=-6:(-0,4)
x=15

(5/6)x+12=(1/4)x-2
(5/6)x-(1/4)x=-2-12
(10-3)/12 x=-14
7/12 x=-14
x=(-14*12)/7
x=-2*12
x=-24

Answer 2

6x+2x=19-16
x=1/2

3,4+2,6=0,6x-0,2x
X=15

(5/6 -1/4)X=-12-2
(10-3)/12X = -14
X=-24
