Answer 2

Ответ:

1)13х=26 2)12y=36 3)11a=33

х=26÷13 y=36:12 a=33:11

х=2 y=3 a=3

4)8к=24 5)9м=45 6)7d=28

к=24÷8 м=45÷9 d=28÷7

к=3 м=5 d=4

7)14x=12+2 8)3y=17-8

14x=14 3y=9

x=1 y=3

Answer 3

1. 6x + 7x = 26 13x = 26 x = 2

2. 4y + 8y = 36 12y = 36 y = 3

3. 2a + 9a = 33 11a = 33 a = 3

4. 16k - 8k = 24 8k = 24 k = 3

5. 15m - 6m = 45 9m = 45 m = 5

6. 23d - 16d = 28 7d = 28 d = 4

7. 5x + 9x - 12 = 2 14x = 14 x = 1

8. 12y - 9y + 8 = 17 3y = 9 y = 3

Therefore, the solutions are: x = 2 y = 3 a = 3 k = 3 m = 5 d = 4 x = 1 y = 3
