Картка No1 5(3x-4)-5-3x-5-4=15x-20 -2(9+2x) + 3x=-2-9-2-2x+3x=-18 - 4x+ 3x=-18 - х 1.-3(2x+6)= 2. 7(x+4)= 3. -5(2x+5)- 4x= 4. | -2(3x-4)+6x= 5. | 4x+3(4x-3)= 3x+2(5x-4)= 6. срочно ​

- 3(2x + 6) = - 3 \times 2x - 3 \times 6 = - 6x - 18

7(x + 4) = 7 \times x + 7 \times 4 = 7x + 28

- 5(2x + 5) - 4x = - 5 \times 2x - 5 \times 5 - 4x = - 10x - 25 - 4x = - 14x - 25

- 2(3x - 4) + 6x = - 2 \times 3x - 2 \times ( - 4) + 6x = - 6x + 8 + 6x = 8

4x + 3(4x - 3) = 4x + 3 \times 4x + 3 \times( - 3) = 4x + 12x - 9 = 16x - 9

3x + 2(5x - 4) = 3x + 2 \times 5x + 2 \times ( - 4) = 3x + 10x - 8 = 13x - 8
