Va rog eu frumosssss și repdeeee

Answer 1

Răspuns:

1. 4( x+1)-5x+7=2x-16

4x+4-5x+7=2x-16

4x-5x-2x=-4-7-16

-1x-2x=-11-16

-3x=-27

x=-27:(-3)

x=9

3(x-2)-2x+9=5x+59

3x-6-2x+9=5x+59

3x-2x-5x=6-9+59

1x-5x=-3+59

-4x=56

x=56:(-4)

x=-14

7x-3(2x+5)-11=4x-17

7x-6x-15-11=4x-17

7x-6x-4x=15+11-17

1x-4x=26-17

-3x=9

x=9:(-3)

x=-3

-9x+8(3x-4)+18-x=36+6x

-9x+24x-32+18-x=36+6x

-9x+24x-x-6x=32-18+36

15x-x-6x=14+36

14x-6x=50

8x=50

x=50/8

3x-2(3x-4)+13+7x=9+8x

3x-6x+8+13+7x=9+8x

3x-6x+7x-8x=-8-13+9

-3x+7x-8x=-21+9

4x-8x=-12

-4x=-12

x=-12:(-4)

x=3

-3x+4(x-1)=6x+2-7(x+2)

-3x+4x-4=6x+2-7x-14

-3x+4x-6x+7x=4+2-14

1x-6x+7x=8-14

-5x+7x=-6

2x=-6

x=-6:2

x=-3

Sper să te ajute!
