Question

3,5x+8=2(x+7) ajudem nessa e nessas outra aii 6(3x+2)-8=-2     essa separa
-3(x-5)-2(2x+1)=-8 me ajudem rapido

Answer 1

3,5x+8=2(x+7)
3,5x+8=2x+14
3,5-2x=14-8
6/1,5=x
x= 4

6(3x+2)-8=-2
18x+12-8=-2
12-8+2=-18x
x= -18/6 = -3

-3(x-5)-2(2x+1)=-8
-3x+15-4x-2=-8
15-2+8=3x+4x
21=7x
21/7=x
x=3
