Question

answer plz
class 8th​

Answer 1

1) -5x = - 6 - 4

-5x = - 10

x = 10

2) 5x = 12 + 3 = 15 x = 15/5 = 3

3) 3m - 27 = 21

3m = 21 + 27 = 48

m = 48/3 = 16

4)8x + 24 + 2 = 42

8x = 42 - 26 = 16 X = 2

5) 36 - 12x = 48

- 12 x = 48 - 36

-12 x = 12

x = -1

6) x = 30

7) m = 1/2 × 4 = 2

8) r = - 99

9) x = 1/8 × -4 = - 2

10) 16 - 3x - 21 = - 14

-3x = - 14 + 5

- 3x = - 11

x = 11/3

i am not sure about 10th one :/

Answer 2

Step-by-step explanation:

1) 4 = 5x - 6

5x = 10

x = 2

2) 5x +(-3) = 12

5x = 15

x = 3

3) 3(m-9) = 21

3m - 27 = 21

3m = 48

m = 16

4) 8(x+3) + 2 = 42

8x + 24 + 2 = 42

8x = 16

x = 2

5) 12(3-x) = 48

36 - 12x = 48

-12x = 12

x = -1

6) x/6 = 5

x = 30

7) m/4 = 1/2

m = 2

8) r/9 = -11

r = -99

9) x/-4 = 1/8

x = -2

10) 16 - 3(x-7) = -14

16 - 3x + 21 = -14

-3x = -51

x = 17
